My car will be striped to the fiberglass. I will be using epoxy primer. SHould I use filler on the obvious areas of repair before or after epoxy priming? Say for example, the Truflex bumper and fenders.

MZMZB, I have the same situation. My car is coming back from being plastic media blasted to the bare fiberglass and I was advised to do all of the repair on the bare fiberglass , including the glazing and do the 2k primer over all of the repairs ,sand , then sealer and paint. Makes sense to me , why would you want a primer between the fiberglass repair material and the raw fiberglass?

SPI says with their product, to apply fillers after the Epoxy is on. Block, recover areas with Epoxy, then 2K Primer. This would seem to encase your filler. I'd do whatever your brand of paint suggests.

I read the SPI tech sheet. I see where they say to apply fillers over the epoxy. I would imagine this would be beneficial for corrosion protection of metals but, is this still necessary for fiberglass?

My main concern is the 7 day window for applying primer or paint over the epoxy. It might be difficult to get the repairs in within that time frame. You know, I'm slow and and work...

I use all SPI products, however on Corvettes, I do all my body work and then apply 2 coats of epoxy followed in 2 days by 2k primer. Works great for me.
