I got the weather stripping for my 64 beetle sunroof, doors, hood and decklid from Wolfsburg West (
wolfsburgwest.com) and it was perfect. The window moldings I wound up using were from German Metric (I think that's their name). Actually, I got most of my stuff from WW. Mostly superior quality but even from them there were a few clunkers. The stuff they manufacture themselves was pretty much right on. The stuff they source from China and other places is often no different than the crap you get generally from the other vendors.
My main complaint with WW was long shipping time -- often a week or more.
AFA painting, I got it sealed and two stage painted at the MAACO on Rt 73 in Berlin. It was a $1200 paint job, and it looks like a $1200 paint job when you get up close. From ten feet back it looks like a million bucks. It's what I wanted (could afford) at the time (maybe five years ago now). No regrets.
BTW, I took the car there completely stripped down and on a dolly with fenders, hood, decklid, sun roof and all the other small bits separate. Some things I had them repaint due to overspray. They didn't argue with me and did it right the second time.
Good luck with your build.
