I wanna put a strip of kevlar down my keel and chines for general rock and dock impact protection. Not planning on shooting class v's just want a little cushion for New River shoals on my Riverhawk. Im using epoxy, but was wondering if it will make a big difference if I sand down to bare glass in those spots or just knock the top layer of gel down then go with it. Planning on a bedliner type coating on top of this, maybe a top layer of 6oz cloth on top of the kevlar. The difference in sanding to bare glass versus the top layer of gel is pretty substantial. If I gotta do it then so be it, otherwise id like to save some time.
