will i need adhesion promotor?

[Steves69LS3]

hey guys i have sanded down an already painted fiberglass spoiler for a repaint and in some spots i have gone through to the fiberglass. does fiberglass need a promotor? will it be a best bet just to cover it in promotor and proceed with epoxy?
thanks

No need for the adhesion promoter on fiberglass, epoxy yes.

Yup, don't use adpro on fiberglass.

just for educational purposes, what happens if you do?

Not much, other than the material will have poorer adhesion than it would have otherwise had.

OK, good reason not to do it!
