I'm getting my CJ5 fiberglass tub ready so I can spray UPOL. Right now I'm trying to seal the outer and inner shell of the tub. You can see the lip that I'm trying to seal up in the pic:
The gap between the outter shell and inner shell ranges from 0 (meaning they touch) to 1/2". My thought was to spread silicon caulk into the gap, let it dry and then use resin to smooth out the ridge you can see between the two shells.
In this pick below, the two shells didn't have a gap between them, just the ridge, so I just used resin to kind of blend it in so it looks like one piece.
Do you think I should now add a fiberglass layer over this and then start to add Bondo to smooth it out or should I just continue to use the resin? I'm using west system 20 resin and adding a microfiber filler so far. Any suggestions are appreciated
