So I am in the process of installed a Kawi 650 pump in my fx1, I have read all of special fx's post on "Another dang fx1 pump thread" and it has been super helpful, how ever like many I am a little new at glass work. Laid my first piece of mat last nite and it turned out great. My question is, I have a thin piece of foam showing where the pump shoe installs at. Should I grind deeper and lay mat in there to build it up or can I just resin over top of this spot? It is only maybe half inch wide and my pump shoe fits in there really nice right now, but if anyone thinks I should do the extra work in this small spot I will definatly do it. Any advice much appreciated.
