Got one from Larrys T Bird Parts. Haven't got car on the road yet so haven't used it. Instructions say not to leave it in place long term. May damage paint? Whole idea is not to damage paint. Anyone have any experience with these? Hardtop weather strip will eventually do some damage to the paint. Have new paint job and want to preserve it as best I can. In the past I always unlatched the top and lifted it off the deck and put a piece of vacuum hose between the top clamps to keep the weight off the paint. Helped but eventually get a grove in the paint form the weather strip.
