I have read through several recent posts regarding fillers and skim coats only to be left feeling "special".

I have a hood for a 72 C10 that has a few dings where the backside cannot be accessed with a dolly/hammer. I plan to fill the dings with fiber strand filler because that’s what I've been doing, but the overall hood is a bit wavy and I cannot get it all worked out with spacers between the braces and the underside of the hood. In my mind a 1/16" or so of filler is needed on 40% of the top surface. The fiber glass filler would be a real buggar to sand at that kind of coverage.

I started this project more years ago than I will admit and have been using Lacquer Primer so that is what I am finishing it with. I'm not switching on the last panel. The hood is in primer (self-etching then lacquer) ...

What type of filler is best to use for the "wave"?

Can it be applied over/under the lacquer primer?

Thanks in advance for helping!
