Update...Finally got the courage to give the fishing line deal a shot. Berkley Fire Line,dropped to 30 lb test from 50,made a couple of 4 inch handles out of 1/2 cpcv,tied 3 ft of line between the two handles,cut that moulding off like a cheese cutter. No damage to the paint or moulding. Left very little residue on the body itself and I could kind of roll the peel and stick off the mouldings with a small nylon scraper,3M adhesive remover for final cleanup. Used 3M 7/8 inch wide moulding tape and the mouldings are now on for good.
If anyone is inclined to buy repro moldings,I would suggest painting them(if needed) first and letting them cure for a few days and then remove their adhesive and use the 3M stuff.Reason for after painting is the paint likes to creep under the peel which might harm the sticky. Plus,the tape will be nice and fresh when applied to the car.
