Fellow modelers...please consider this a sort of public service announcement.
If you're tired of paying $15 for GW's brand of spray primer, I stumbled across an insanely cheap solution while visiting my nearby Home Depot. How cheap are we talking? About $0.97 per can of Quick Color. That's how cheap.
And since I left my primer in California on accident, I decided to stock up...
I tried it out on a figure and found that it worked really well. The only thing is that you have to press on the nozzle a bit harder than you do on the GW stuff....but for less than a dollar per can it's a sacrifice I'm willing to make.
