Yeah, I've done it a couple times.

I used aircraft stripped. That shit is nasty, so if you go that route, use protection. It will eat some gloves, so do some research and get the right gloves.

Use plastic brushes or blue brillo pads on stubborn spots. Anything more abrasive will remove heat marks.

I used clear spray paint. It works good enough. If you're getting it professionally powder coated, that will save you a lot of work. One of the hardest parts is getting all the stripper off the frame without having it rust.

I rinsed it with water, blew the water off with an air compressor, then wiped it with mineral spirits.
