You may be able to use conventional paint polish & wax to correct the damage to the bra. That's worked for me before.
I pulled a clear bra off a 968 earlier this year that had been on for 10+ years. Acetone, heat gun, plastic razor blades and lots of patience were all necessary. When the bra came off, the paint underneath had been protected so well that it had not faded... unlike the rest of the car. Hard to see here, but there was a distinct "horizon" about 4 inches up the hood.
