I spray painted over sealed eps and glassed it today. The blank had some rough spots and the RR epoxy foamed up a little really quickly. (it is a super hot day, 98 degrees.) So the rough spots didn’t fill in all the way in places, what should I do? I was thinking drilling and then injecting resin into the patches, but they are mostly small. Does this mean I’ll have delams in those spots?
Epoxy will froth (foam?) if you move it around alot on the EPS.
Also, in pin point locations, and some foam more than other, the foam will outgas and make a bubble if the temperature is rising while you are glassing.
