At that price, it is no wonder they call it "spot" filler and primer. You can only afford to fill and prime spots with it ...

The Plastikote Sandable primer is cheaper and works real well.

Yea, that was the one big drawback to CarQuest! However, they have the stuff, all the time. The other place around me that had it (a backwoods auto parts store) has it for $6 but only stocks one can at a time, and the guy looked at me real funny when I asked if I could special order some.

I stopped at an O'Reilly's Auto Parts store today for something else, and found both the Dupli-Color primers. The new "Perfect Match" one was 8oz for $6.95 while the old big can was 11oz for $3.95!

I tried for the first time Rust-Oleum Painter's Touch Ultra Cover 2X Coverage Primer. It dried in about 30 minutes and sanded well. 3 coats, sanding in between, got rid of BT spirals. 2 coats on top of Fill 'n Finished fins and the surface is very smooth. I think it was about 5 bucks for a 12 oz can at Home Depot. I'm getting a lot of mileage out of the one can so far.

Might have to try that Bondo primer.
Seems a little light on solids, but appears it would dry extremely fast based on the solvent package.

Alrighty then...

I tried the Plasti-Kote Spot Filler & Primer on a balsa nosecone that had been "hardened" with CA, sanded smooth, coated with diluted FnF, and then sanded smooth. Although I thought my prep was good, the Spot Primer went on and dried quickly allowing me to sand within two hours to reveal the flaws in my prep. I've already sprayed a second coat of Spot Primer and am waiting for it dry so I can sand it again. Today. Not tomorrow, today.

Lessons learned:
1. PK Spot Filler & Primer is sand paper friendly.
2. PK Spot Filler & Primer dries quickly.
3 PK Spot Filler & Primer is expensive.

I tend to build in a mass production way...assemble a bunch of kits, fillet the bunch of them, prime them, and then wait for the primer to completely cure. Seeing as how sanding is nobody's favorite thing to do, there they would sit...primed but not sanded...until I decided I wanted to actually launch one or the other of them.

I think with the Plasti-Kote I will be able to build in a serial fashion and actually complete one bird before starting another. This will be a good thing.

Good, fast primers can be sanded in about an HOUR, not in the same DAY !
Generally all my coats of primer and sanding are done in the same day.
