How do you make Sanding Sealer / Grain Filler?

Hello there :) This is my first forum post so please be gentle ;) Okay, here's the skinny. I am doing a zakk wylde paint job on my stagg strat. I've removed all the paint and sanded it down. But I have some scratches on it (from the sanding) and a few places where I went in too deep with the sandpaper and removed some of the old sanding sealer. So, I need some sanding sealer / grain filler in order to make it a nice smooth surface so I can apply primer to it. Here's the problem. I live in a country where there is ABSOLUTELY NO DEMAND for sanding sealer / grain filler. So there is nothing like that in Bulgaria. And I need to know how I can make my own. (all of the carpenters here sand it and put on some lacquer and it's an awful finish but that's how it is here) Sooo, can any1 please help mee.... :) I really need something that is a good substitute of grain filler / sanding sealer.

. Elmer's glue mixed with fine sawdust may work, depending on the primer you will be using.
. Use thin coats of primer. Apply thin coat, sand, apply thin coat, sand, ...
. [ Bondo] would probably work.

Bulgaria?? Wow, Zdraveite!
(I love google.)

The sealer I used on my boomerangs smelled like varnish, and went on the same.

Maybe thicken varnish somehow?

Or thin down some glue?

Whatever you try, make sure you test it on scrap timber, or a hidden area, first.

Zdravei ;) Well what exactly is varnish (what does it do I mean) In Bulgaria we have all these different names for stuff. I think varnish means lacquer right? But thats the stuff that goes on the top. I need to make the stuff that goes under the primer and right after the wood.

Yes, varnish goes on top, but is slightly different to lacquer. See these wikipedia pages:
