i am repairing a dent in my rear quarter panel and i have laid fiberglass over the dent. i sanded it down as smooth as i could get it, but when i sprayed the primer/filler, some tiny holes appeared. i guess these are just tiny imperfections in the glass.
what is the best way to fix them? should i apply some glass resin and sand down? will several coats of the primer fill them in?
