Years back I changed the bottom on my 17 1/2 Tatman from UHMW to glass/epoxy with graphite. I used fiberglass cloth with one layer of kelvar. Never did like it near as much as the UHMW. Now I am slowly repairing/refurbishing it and am thinking of stripping the bottom to the wood then using Wetlander or UHMW. Even without the kevlar it would be quite a chore & with the kevlar probably much worse. Anyone used heat to take a epoxy/ cloth layer off? Did it work?
I tried sanding my bottom when I first started the graphite coats and had one layer not lay out as smooth as I’d wanted. I quickly abandoned the idea and just kept coating over it. Sanding all the epoxy off the bottom of your boat will be a miserable process at best. Since epoxy doesn’t go bad and I’ve heard rumors of uhmw with an epoxy binder on one side maybe that is your answer? I just wouldnt wish sanding epoxy off on anyone.
I removed CoatIt epoxy coating. A heat gun and scraping worked best. Don't know about removing Kevlar cloth. I suspect sanding would be necessary.
