Ezekote is water based Ken. Dilute it with water and you can use it as a sanding sealer and . Used neat it's ideal for sealing hulls inside and out, with FG tissue as required, and it don't pong or need a so 'er indoors can't complain if you work indoors with it😊 When you're done just wash the brushes in warm water.

We have a product here Peter which is almost the same thing. A common brand is International Everdure which is a sealer and preservative used inside wooden boats. It is a very thin epoxy resin with anti mould properties which you mix 1:1 with the . You can just make a batch and pour it into your hull and tip it around to get it in all the spaces ( hull needs to be reasonably sealed before doing this as it will find its' way out like water). You can work it for about 6 hrs on cold days and brush any spots you have missed with what goes to the bottom. The remainder settles to the bottom of the hull and makes the keel like a rock, (you can remove excess with a brush and paper towels if you don't like that idea. The beauty of this epoxy is that it finishes as smooth as a babys' bum and you can even coat the decks with it as well (did the deck of my ST and you would think it's varnish) Another brand we have is Norski which is the same sort of product. Reasonably expensive but magic stuff (smells strong for a few days then nothing, smooths out nicely too) John B

Hi Martin, The FG refers only to the very light glass tissue, which is completely inert. (FG doesn't automatically mean Epoxy Resin these days!) In future perhaps I'd better use the abbreviation GF for glass-fibre (NOT Girl Friend😉) instead? The beauty of Ezekote is that it is not epoxy, does not need a heat generating and is water based. Deluxe advertise it as 'Foam Safe', that's even printed on the bottles.😊 The Foam glue I recommended is also explicitly described as suitable for Depron, amongst others. That's why I mentioned it. I've tried various Deluxe Materials products and they all perform 'as advertised' 😉 Cheers, Doug 😎 BTW Both products also dry crystal clear.

40'' Seaplane Tender, new build F

Finished fairing hull and correcting chine curve. Glassed hull tonight using 6oz cloth and West System epoxy resin. Took a few hours to dry even though I was using fast due to cold weather, and when still flexible, trimmed off the excess cloth. Will give it a day and de-wax and sand it before giving it another coat of resin, then it will be on to sanding, filling and fairing again. Hull weighed 720g before glassing and 920g after ( probably end up around 1kg filled and painted)

Glue

Martin - don't you have to use something like Mek Poly for ABS . I bought a model tug kit with ABS hull (George Turner) - ordinary polystyrene cement did not even touch it The UHU version which is stronger than the other types did not work. Tried 4 different glues with nothing doing then used Mek Poly - instant bond. Been told that its actually used as a for polyester resin - so got 500ml of (cheap) but have not had cause to use it yet.
