all life is a learning experience, i have been working on my '48 merc coupe for almost 8 yrs. we had worked the hood up until the final sanding before paint, it seems like a certain brand of self-etching primer is not compatible with some of the better primers. after 4 yrs it separated, had to strip the entire hood down to bare metal and we're now starting over from scratch. hard lesson learned!

one foot after another and we go on.

I have learned to get all painting supplies from the same manufacturer for best results. I did not follow my own advice on a couple of painted items on the display engine and the top coat wrinkled up really bad. Back to square one.

Something has change in paint chemistry. In most paints 15 years ago you could touch up or recoat 24 hours later with no problems . Now days you have maybe two hours. After that it will lift and wrinkle unless it has completely cured (as in seven to ten days in good heat)and hardened . This is true in spray cans and auto paint top coats alike. I had to reshoot a pickup door that was shot three days earlier ,what a mess! Then this last weekend I was going to do the lettering on my 1941 license plate. the base green was a two day old perfect spay can job. I just started the white lettering when I noticed white was starting to lift and wrinkle down to the primer.
