I can't really justify spending more to get another brand of Flat Black...
With the WalMart primer and Flat Black over it... the stuff is as good as any other FB paint tried so far, and miles better than Testors FB. (I have found that it finishes MUCH better with the primer under it - almost gets a slight satin finish... very nice IMO)
At under a dollar a can it's really hard to beat, and easily accessible of course.
I've not tried other colors from WM so can't speak to those. I'm still stuck on Dupli-Color for my main go-to for now (but teetering on the airbrush world sooner than later).
Just looking at a couple spoons I painted with FB and figured it deserved a fresh post
I've read that the white primer is good too. I've only used the grey but will have to grab a can of white to try as well.
