I have a mid 80's Puch 170 Touring bike since it was new. I want to disassemble and repaint the frame. My preference is to spray it in my garage. I'll rig up a makeshift booth with tarps to do so. I have looked at number of utube videos, but still have some questions. The frame is in OK shape but does have many thousands of miles on it and associated scrapes and chips and a little rust but nothing major. It was a commuter for many years and a weekender after that. The frame is 4130 CroMo lugged construction. The plan is to paint it Coleman stove green with an off-white filling on the head tube and maybe a same color panel on the seat tube. And highlight the lugs with a small modellers brush. The questions I have are:

Will chemically stripping the paint to start be harsh on the brazing material? I think I would have to do considerable sanding even after that.

Should I try to remove the headtube badge or just tape it off? It is riveted on so I guess I would need to tap the holes and replace those with screws.

I assume doing the cream filling will have to be done by either taping off the lugs and spraying over the primary color or taping off the headtube in the first place and then re-taping and spraying.

I am thinking about using automotive primer as the base over the stripped metal, will any type do?

Will enamel paint give a reasonable finish?

The internet is a big place and I get lost easily so if anyone has a good reference I will happily have a look at it.

Thanks
