You guys, I build polymer molecules and in the past have formulated paint. Some people consider me a finishing expert.

Make sure you use the strippers outside. The Jasco has methylene chloride in it - I looked up the MSDS - and that will make you stupid if you breathe the fumes. It's also a carcinogen. Nasty stuff.

I wouldn't let ANYBODY sandblast my frame. Even if they didn't blast a hole clear through it there's a chance they could weaken it. Ungood.

Powder coating is cool but what if you want to touch it up? If it was me doing it I would just go get some Krylon Tough Coat or some other acrylic (yes, acrylics are harder) and shoot it with that. The trick is to go slow and apply multiple light coats instead of one or two heavy coats. Use a primer underneath for maximum adhesion, and sand lightly after the prime coats to get it smooth. Let it dry for at least a week before putting it all back together. If it gets scratched just scuff sand it, spot paint the repair in, and rub it out so you can't see it. Easy.
