I was just going through some old issues of Scale Auto Enthusiast and in the October 1998 issue, there's a good article by Rick Hanmore on promo restoration. It's a 5-page article with plenty of good color photos, tips, and ideas. If you've got a stack of back issues of SAE, dig it up and check it out!
Very cool Snake! I read your post, then went and dug out my copy and checked it out also. Yes it's a very good article! A lot of good tips and ideas indeed!
I have most of the issues all the way back to early 1982. I started going through some of them and highlighting the articles that I was interested in, and puting them into a database that I spent too much time setting up. Then wasn't totally happy with the way it turned out. I guess I'll have to keep on tweaking it.
