Being in the rust-belt northeast, we get a LOT of rust problems. But they are mainly a lower-body or frame issue. Sure, I've seen some vinyl top cars with bubbling under the vinyl, or 20+ year old cars that have pillar or roof rot due to long-neglected vinyl tears or seam lifting. But vinyl tops still seem quite popular up here and rarely is it a major rot issue....more the exception than the rule in my experience. I will say that when it HAS been a big issue, it has been on AMCs...but then, I don't deal with many 20+ year old big three cars, so the issue could be a matter of vintage vinyl materials. In any case, if the opportunity presents itself (as in finding my piece of missing trim, and funds availability) I hope to re-install my car's Cinnamon Vinyl Top as soon as feasible....first, because it's original and correct for my car, and second, because it's not a contrasting color....it will blend in just fine without breaking up the car's 'flow'...and third, cuz the car will rarely see foul weather and will be garaged when not on display. The chances of it causing real problems are very remote....and lastly, I'm sure modern vinyl materials have improved enough to eliminate any moisture penetration and trapping problems. Your mileage may vary. :) John -----Original Message----- From: Eddie Stakes [mailto:eddiestakes@xxxxxxxxxxxxxxxxxxxx] However, it is the sole reason that every AMC I have ever owned (with the exception of the 77 Matador Barcelona) I tear off the vinyl roofs. It will save your vehicle from roof rot. Yes, rust forms along the rain side moldings, and bottom of front windshield and lower rear glass. This probably don't affect many parts of the country, except those with high humidities like here along the gulf of Mexico. I don't know about the other coasts. But since most of my cars, including showcars, are driven, vinyl roofs are removed and painted over. Some, like 71-72 AMX/Javelins with fake split t-top vinyl, I have POR-15ed those areas, and it looks great and passes muster at judging even though not stock, looks like a shadow mask roof. Good luck whatever your decision, I would guess some others here in high humidity areas could comment on this type of rot and rust. ------------------------ Yahoo!
