Anything thinner than glazing putty?

[Risu]

I've been building up a piece that I'm working on, first with foam and styrene, then with bondo, and now trying to get a smooth finish with glazing putty, but no matter how many times I go over it with the putty, I keep getting little pock marks and pits all over the surface. Is there anything thinner than glazing putty that I can fill those spaces in with and smooth out the surface?

filler primer?

If I go with that I'll have to be really careful about masking certain parts so that they don't lose detail. What's a good brand/place to buy it?

auto parts store sell it. But, have you been applying the glazing putty with a razor blade? That way you can apply it in a controlled manner just like wall spackle.

Spot putty is meant for filling pin holes and very small imperfections.

I use the green version from 3M.

It doesn't use a hardener. It is air dried.


See if you have a finishmaster in your area.

They are a supplier to the auto body industry.

SEM makes a really good high build primer spray can

that you can get there.

I've been using the air-dry glazing putty and applying it with an old driver's license. It's worked pretty well for the most part, except parts of the putty I guess are leaving air bubbles and recesses inside when they harden which are exposed again when I sand it smooth. The resulting surface looks like this no matter how many coats I put on.

Thin the putty with acetone...

I'll keep that in mind to speed up the process on the angled section. The filler primer is working pretty well, despite some of the really large pits, a couple coats filled in mostly everything. After I sand it later tonight I should only need one more coat of the primer and the sides will be done. Thanks for the advice everybody.
