Why is there a bumpy finish after you prime nude carbon fiber with epoxy primer?
Jax490
carbon fiber is assembled of the layers of fiber and laminated (buttered) with EPOXY resin
epoxy primer reacts with the resin as they are the same chemical base.
the epoxy in the CF is re-activated (kinda) and swells on the immediate surface where the trapped chemicals from the incompleted outgassing during lamination has been laying in wait for somthing to "soften" the coffin they have been trapped in.
think how epoxy is typically applied to 2 surfaces..allowed to tack/dry.. then the 2 surfaces are mated together (laminate counter tops, carpet on speaker boxes etc).
your solvent rich, epoxy primer breathed life back into the old surface.

On raw fibreglass, epoxy primer is necessary. On gelcoat, polyurathane paint sticks well, provided the surface is well sanded and cleaned with acetone, but pinholes and cratering can be a problem, so where a high standard is required, priming the gelcoat with epoxy is recommended.
