Paint brands
I've used a lot of Pactra rattle cans, but not in the last 5 years or so, having had better luck with Parma Faskolor. The Pactra paint seems to be brittle and chunks off easily, even though I scuff the inside of my bodies. The Parma paint seems to stay flexible and doesn't come off even when the body is severely battered.
I can't get some of the colors that I want in Parma, though.
Anyone care to post why they prefer the brand they use?
