Jockscott I think it's because I use unstarched .75 oz cloth. It is thin and just falls loosely Starched is like a starched shirt stiffer and less malleable.

Thank you for your insight Brightwork. Amazing you were able to get the cloth adhere evenly on your boat. If you look at my earlier picture with only the bottom and sides done, you see all that extra material I had to cut in and away at the bow and stern. I can't see it working as it did on yours. Also I made the mistake brushing excess epoxy on the bottom. It has taking a bit time sanding it all smooth. I will add one more coat of the sealer once I am done sanding as it goes on like water as some spots the cloth as come away and/or I sanded through the cloth.

Cdnfurball. Ok.. so... you mix your resin in 50/50 mix. Then you denatured alcohol in an equal amount to the total mix of the two resins combined to the resin you have just mixed. It will look cloudy...but as you stir it and mix it, it will clear up..that's when you can apply it. As it is diluted it gives you lots of time. I do not resin the wood hull at all. The first coat of resin alcohol mix you put on over the cloth as it lays on the hull will sick the cloth to hull as it soaks in. Let that cure when you are done applying. Then brush a second coat of the same mixture. Then I add one more coat again. The end is a fiberglass hull that needs very little sanding.

K guys... just a note...you should not be pinning the cloth to the boat. Lay it over the hull and then start to apply the thinned resin as the video shows in an out ward motion the cloth moves and stretches a bit here and there to make the contours. Do one side then the other from center of keel out. This hull was done with one piece of .75 oz. if your cloth is to thick you will have more problems. If you pin it you will be fighting it.

I first dropped the cloth over bottom and straight sides, secured with pins and applied the epoxy to cure. The bow and stern section were done after proper curing of the first stage. I wanted to be sure the general orientation of the cloth remained unaltered. The cloth did not adjust well to all the curves and inverted shapes of the hull. I am not sure which type of cloth I got but it was the lightest available. I had applied 2 coats of epoxy water sealer first. In hindsight this may have been overkill. Since this is my first attempt I can accept I had to learn my lessons.

A fellow builder suggested draping the cloth, use clips as weights on what would be the scrap glass. If needed, tack a few spots with a lil c.a. Then the epoxyโฆโฆ.
Weโll see how that works out on current projectโฆ. Stay tuned on a few months
