Perhaps you have answered the question your self, wet and dry and after a couple of coats you should find it smooth and without blemish. This is the time to ensure there is no dust around. A good idea is to try and make a shelter around the boat and wet it before giving it the final cost of a good quality gloss paint. It really is just a matter of perseverance and you should have a great finish. Good luck! Peter581
After modding my Sea Queen with the new prop shaft I decided to smarten it up as the previous spray job I did was not too good, well I have had terrible trouble with it, the first attempt saw the original paint raise as I sprayed it with a primer that was supposed to be safe with all paints, so I removed as much as i could using the heat gun and a scraper, after sanding down and filling, I started again, i had some small patches raise up where I could not get the original paint completely removed, but after letting it dry and some wet and dry I managed to get a good primer coat on it. I then decided to spray it all white, so as I have always had good results with halfords own brand I gave it some light coats of white gloss, I was unable to get a reasonable gloss finish and it also needed some more filling, funny how a gloss coat show up all the defects, well subsequent attempts at spraying were useless, run after run and a poor gloss finish. All I can think is that I could not have had the area blanketed off in the workshop warm enough and the thinners in the paint was not drying as it hit the boat and just ran. I am now half way into sanding it all back and have decided to hand paint, What is the best paint and method to getting a near spray paint finish by hand brushing?
Hi John, Lets take your questions one at a time. Surface prep. Close joints are always good but not essential, glueing plastic involves a form of welding, ie the surfaces melt together forming a filler as well as a glue. Plastic weld is a model railway product which is very good, it's a liquid applied with a brush and the pieces are held until the liquid evaporates. Prep all surfaces as there might be release agents and / or fingerprints on the surface, washing up liquid is great for this, also when ready for painting wash again and lightly scuff the surface with fine wet and dry paper, (600 grade). Epoxy. Is not a good glue for plastic hulls and superstructures as they flex and move, epoxy is brittle and will fail over time. Finish painting with a plastic primer, (Halfords) this gives a flexible basecote, then paint as desired, i use car type acrylic paints, if you want a colour not as a car, you can get paint made up to your spec. In short, Liquid poly glue, clean before the build and when ready for paint. Hope this helps Mark
After many distractions and accumulating 'stuff' to go in and on the boat I finally got around to tidying up the hull this week. After flattening with 180 / 240 wet and dry I sealed with Ezekote flattened again then sprayed with a professional grade primer / filler from the auto branch. As usual this showed up all the pits so I filled them with Revell Plasto and primed again. After going round this loop a few times I was (reasonably) happy and flattened with 600 W&D. Then sprayed on Royal Blue from a giant rattle can, also from the auto pro market. Flattened off with 1200 W&D between coats. I have Tamiya Royal Blue acrylic for my air brush as well but couldn't be bothered to set up the compressor🤔 Can worked pretty well though. 👍 Last pic shows the 'Before'! Will leave the final finishing, nameplate and lacquer coat until I have finished the internal fitting out and the cabin. Have decided to plank the cockpit with mahogany😲 just ordered from Krick! First attempt at planking - Wish me luck! I like the blue hull so much I think I will just mark the waterline with a red (or white?) boot topping stripe. Comments welcome. Cabin will be white with a blue roof. Now to continue with the new prop shaft, old one is showing signs of wear at both ends and rust at the wet end 🤔 Anyway it's got an imperial thread which is useless when all my brass props are metric. More soon, I hope 😉 Cheers Doug 😎
Yup that's real GOLD, and I have used for fifty years on real boats as well as models. I rub down with 2500 wet and dry after the final coat has hardened for at least two weeks. Then use a beeswax polish on a slow orbital polisher or by hand. It's really worth the effort. Best of luck Colin.
As an afterthought when you have rubbed down with wet and dry used wet wash the paintwork off well allow to dry and then use a lint free cloth to make sure all the old paint dust is gone. Make sure you work over a surface you do not mind being marked since the drips from rubbing down make an excellent paint on an absorbent surface!! ( yes I made the mistake so I KNOW). Its a very messy process but well worth the effort.
Exactly Haverlock👍 wet with washing up liquid between coats is what creates the polishing effect and final gloss. Something I learned the hard way back in my car restoration days. Dry sanding creates more of a 'silk/satin' or worse matt effect. 😎
use 600 wet and dry wet for first few coats then 1200 wet then after last coat wait a few weeks and use something like "T" cut ( used to restore car paint). The wet and dry is better used wet ( with a dash of washing up liquid in the water) since it cuts down on the clogging of the paper.
Hi Scotty Welcome to the site. Just had a look on the web about Sanson Tugboat see pic. As you intend to allow the planking to show I suggest you use G4 Pond Sealer (Bondaglass Product) on your hull after you have sanded smooth to shape. You can also use on the inside. It's a polyurethane type so can be easily brush applied in thin coats and sets rock hard as well as being totally waterproof. You can overpaint if you carefully roughen the surface with wet and dry paper. Once the colour is dry and any decals applied you can apply a final coat of G4 over the whole hull and it will be protected against the odd knock etc. As Doug says acrylic is easy and pleasant to use for the upper works and can be sealed with acrylic clear lacquer, I find silk works best on a scale model. Sounds like an interesting project is it a kit? If you start a build blog we can watch your progress and you will be able to ask for help and advice as the build progresses. Please keep us posted on progress. Enjoy the build Dave
Hi Chris, A way is to score the back of the piece to be curved with a sharp blade, depending on the thickness of the ply. Also lay a few pieces of kitchen paper on a flat surface and go over the piece with a rolling pin pressing hard to get a curve into the ply. Wetting the ply, test some scrap ply and see if it delaminates, if not wet it and put it round a former such as a paint can hold it with bands or straps until dry. Hope this helps Mark
Wet and dry sandpaper and lots of washing up liquid go down through the grades of paper til 320 grit The worst thing you can do it try to send it all back Better to send and get a good base to start again with spray paint
So If things are still not going well It may be better to take the moulding you have and work from that. Chuck all the moulding away . Flat board screw the hull down on the edges. Filler and sanding and keep going til your happy with it then finer and finer sandpaper then wet and dry and finished off with G3 polish then wax and pva then make the mould. Bearing in mind any blemishes in the mould will be in EVERY moulding taken.. Making the mould is not as hard as you think.
Hi John Having looked closely at your hull construction and joints it would appear that over time the joints have failed. I have a Mercantic with exactly the same problem. If you can sand the raised joints flat then there is a method we use on our mahogany planked schooners that provided a water tight seal and produces a very high shine finish of great strength and resilience. We use G4 pond sealer which is a polyeurethane paint available from Garden Centres. ABL Stevens are my local supplier http://www.resin-supplies.co.uk/sealants.htm Its a one-pack polyurethane varnish hardened by moisture in the atmosphere or from the material being sealed, used as a sealant for timber or a barrier coat for concrete, preventing resin being attacked by moisture or alkali's. It's brush painted, touch dry in a couple of hours, dried in 24 hrs and is fully hardened in one week. We usually apply one coat then after 24 hrs wet and dry any blemishes and apply a final thin coat. We also coat the inside of the hull. If your hull has thinned in places then you could use tissue or thin glass cloth inside the hull to give added strength as others have suggested. Hope you manage to get the result you require. Dave
Hi John, Suggest you sand as this will flatten the planking, no doubt each plank has curved slightly as the wood had dried out. Hoover out all the dust from the cracks and fill with a mahogany filler and re-flatten. The inside of the hull will also need varnishing to stop the wood drying out again. Would not advise wetting the planking to raise the grain as is normal practice as this might swell the wood and loose the filler. First use a good quality polyurathene varnish, brushed on but avoid runs, lightly sand to give a key before recoating. At this stage do not worry about the brush strokes showing. After at least 8 coats use wet and dry paper to sand the surface flat. Now apply a yacht varnish that does not dry so quickly and brush strokes will on the whole disappear. I suggest at least 3 coats to finish lightly wet and dry between coats. The more coats you give the deeper the shine. Use a good quality brush, a cheap brush drops hairs and does not give a smooth finish. If you look at my harbour and look at 'River Dance' you will see the finish this method can achieve. Good luck and hopes this helps. Vic
Hi Martin, Bin round the Talisker ? 😉 @stwdv; ignore what comes next, go to the last paragraph 😎 The scale effect (as I understand it) has nothing or little to do with shine! It refers to lightening / fading the colour to fool the brain into thinking an object is further away than it is, and therefore think it is larger. Look at any landscape photo or 'in real', hills or forests further away look lighter or more grey than the green ones in the foreground. There are pros and cons to both as Dave says. Cellulose is history, except from some nitrated cellulose solvents. In the car restoring days of my youth I remember getting crinkling if I used cellulose thinners from a different manufacturer than the paint 😡 @stwdv: if you do it veeeery carefully in very very thin misted layers (barely wet) you CAN put put a different paint on others BUT you need flat of and prime the old paint first. Pay a bit more for your primer (universal types) and ensure that the coating is absolutely complete and totally dry and hardened. Some combinations work better than others. But essentially it is better not to mix and match. It's essenentially the thinners that does the damage, less is more sometimes! Try to avoid cheap aerosols, paying a bit more avoids a lot of heartache and extra work, or throwing things in the bin 😡 They tend to have a fairly wide spread on the nozzles which wastes a lot of paint through over-spray. They also tend to be a bit thick and difficult to control the flow which can cause 'orange peeling or even runs and 'splodges' if the spray stutters. To counteract this one has to spray thinner; i.e. back off more from the object - which causes more over-spray. 🤔 The little spray cans made for modellers are much better than this in all respects than the cheap jumbo cans from the hardware store. Get a decent air brush for the big bits, then you can control the paint viscosity, flow and size and shape of the spray cone. takes a bit of practice but is worth it if you intend to build more models. But I suspect you wanted tips on the preparation! So let's cut to the chase😉 Sanding and filling are the buzz words. Checking the surface very lightly with your fingertips is much more sensitive and accurate than relying on your eyes. 🤓 When you think you got it right put on a THIN coat of primer (matched type to the finishing paint!) and you will soon see the spots you missed! So back to the filling and sanding. Use a very fine filler at this stage. Prime again and flat it off with 240 to 400 wet'ndry. Take off the residue with a damp sponge and dry!!! Go round this loop a few times and when eyes and finger tips agree you are ready for the finishing colour coats. Thin, let dry. Check for blemishes. Fix if necessary, flat off -> next coat. ALWAYS take note of paint can drying / hardening notes. Don't rush or you'll end up doing it again 😉 Hope this helps, bon chance mon ami 😎Doug PS my larger model (mostly warships!) I use resin based paints in half litre cans from the DIY shops and an airbrush. They are hard wearing, come in all colours (RAL codes) and finishes and are easy to mix and thin with turps or white spirit. They take the enamel for detailing with no problems. Snags: take longer to dry, but they are hard wearing and cheaper than millions of 14ml cans 👍
