Has anyone in the States found a similar product that can be used and if so where? I searched for this product and I believe it is only available in the UK?

QuoteMy box is constructed mainly of 3/4" WPB ply and originally coated with a polyester gel coat to give it A) Texture and B) weather protection (well, if it works for boats and all that!)...Roof - Gelcoat cracks with temperature changes allowed water to get into all joins. New roof....Do not use any form of gelcoat - the thicker you apply, the more brittle it becomes. Also, there is very little movement with this, so expansion and contraction WILL crack it allowing water to get to the wood.
Quote from: anotherwheeze on Jun 21, 2008, 09:33 pmThe primer I was referring to is the Isoflex one. Once dried, nothing, but nothing shifts it. So my cunning plan was to use this and then gelcoat, rather than applying gelcoat direct to the wood as before. I just got rather impatient in some areas and proceeded to apply gelcoat before the isoflex primer had fully cured. Trouble is, I don't know how many other areas were affected Time will tell.You can get a great texture from Isoflex rubber and chopped strands. So IF I were to build another box (probably a met box after seeing KB's!) this is how I would do it with 99.9% confidence. I'm at around 75-80% confident with what I have done (was 90% before the roof cracked!)
