Re: Penthouse pop top repair ideas?
I would think any quality Corvette or Ferrari shop could repair the tops to an exceptional quality that would never crack, peal (or leak) again. Never leak, as long as it's not the seal or material that's the issue.
I seen the quality glass work that my local Ferrari shop does, it's outstanding and not as expensive as you might imagine. You just need a shop that understands how to fix fiberglass in the reverse order to how it's made, and in my experience, that's usually Corvette and Ferrari shops. But a bad fix won't last long at all.
BTW, if the top clear coat is cracking, it was either the wrong clear used, bad fiberglass and/or gelcoat work, or the top is flexing too much, which would indicate bad install.
