I have located a fairly local PPG dealer who has the hardener recommended by PPG, so I will be getting some later this week. I plan to try a small amount on an inconspicuous place and see how it works.
As far as mixing chemicals, I am very careful. I have a Masters in Chemistry, emphasis on organic (which is what all these paints are), and spent 20 years teaching chemistry.

I am currently digging back in to a 1953 3800 (one ton) with a nine foot bed. I've owned it since 1979, and drove it until 1982 (or so). My wife got me involved in restoring it back in 2002, got the body removed and the frame redone, then things came up. Now I am retired and starting again. If anyone is interested I have photos on Imagur (
