I know Scott and everyone else loves Velejo primer. I've never had good luck with it. I use Mr. Surfacer 1200 thinned with Mr. Color leveling thinner. The paint really bites to it. Good stuff. Tamyia fine primer is awesome stuff but it's a little pricey. For the same money you can get twice the amount with Krylon ultra flat Camouflage spray paint. Works just as good as Tamyia primer and it takes very little for full coverage.
