Painted targa tops

Hi.
Has anyone had their glass targa tops painted?
How was it done and how is the paint lasting?
Other option is vinyl but I'm not sure how close they will be able to match '93 blue metallic.
 
I see this product claims to work on glass:
Bulldog® Adhesion Promoter  is designed to promote paint adhesion to all automotive surfaces, even problem plastics. It works equally well on all flexible or rigid plastics, fiberglass, aluminium, glass, chrome, vinyl, galvanized metal, and painted surfaces. Bulldog acts as a tie coat by allowing several different surfaces to be painted at the same time to assure a smooth, flawless, durable finish every time. If added to the paint, it will perform as a flex agent, promoting more flexibility on plastics.

I have a spare set of tops I've toyed with painting.  There is some info on the oc re painting them, but from memory they weren't doing anything special, may be worth a search.

That actually looks alright have you thought about sourcing fibreglass or carbon fibre t tops and painting them instead?

What about using vinyl wrap?  Much cheaper solution and there are so many colours available now, there's probably a really good chance you could find an almost perfect match.
 
EDIT: Duh!  Clearly I didn't read the first post properly since you mention the possibility of using wrap!
