Should I Be Worried

I sprayed 2 coats of SPI epoxy over some panels that had filler spots that were sanded to 150. The outlines of these filler spots show through the epoxy. Its been drying a couple of hours now.....no change. I'm not that concerned considering I'll be putting a couple of coats of Slick Sand over it.....but I just wanted to know if I should be concerned. Thanks.
No worries at all, the filler is porus so the epoxy will look a little funny untill it's sealed up. Shoot your surfacer and rock on. Epoxy or any coating for that matter will be affected the same when applied over a porus surface-it's just much easier to see the difference with the epoxy since there's some shine to it.
