Primer

What kind of primer does everyone use? do you use Brush on or Spray? or do you use an airbrush? just trying to get an idea

Rigus

i use white primer alll the time from army painter cans

Michael can cringe all he wants, but I use walmart buck a can flat black spray paint.
White, I generally use GW.

u dont like the amry painter primer

I usually use some cheap model primer from hobby lobby, flat black

dupli-color sandable primer is the way. prepare for salvation.

I mostly use black primer from GW but occasionally use ones from hobby lobby as well. Actually am going to try airbrushing on tanks to see how it looks.

Unless you are using a brush on or air brush primer, airbrushing is not priming. It will stick the same as just putting on a base coat.
If you are using a primer, great, just wanted to not confuse anyone.
