Hi, I just wanted to post this because it seems like from my forum searches, a lot of people were interested in the same subject. So I thought I would post what I have, and eventually I'll post pictures and results.

I am essentially trying to clear-coat a raw aluminum frame. Because it's a vintage Vitus frame (aluminum with bonded lugs that will not withstand heat), I can't powder coat it. If I could, I would, believe me!

But, if you are like me and you can't, or if you just want to go the cheap route, there is this product: http://www.vhtpaint.com/products/adhesion/

It's a clear primer. It should stick way better than trying to paint clear-coat right on the frame. I'm going to start by using their prep spray, then the clear adhesion promoter, and then clear-coat on top of that.

Anyway, I'll try and post results as to how this turns out! Either way it's going to look better than the chipped DIY spray-paint job that it had. I can't seem to get spray-paint to stick no matter what I try.
