I am painting with a friend(he got experience) and I have done some in the past 2 stage years ago. We are painting inside trunk, and hood, door jams. I painted the firewall already. Just want to get the idea of how much painted needed and what brands are new and up to date. We haven't started sanding yet, and it does look like there is maybe to sets of old paint on this car. So maybe we won't make it down to bare metal. Just wanted to know what paint technology is out there now, and is giving good results, sometimes those paint reps. just want to sell you things you don't need.
