If you are sure that there are no iso-plastics in the clear coat - then you might be able to use heat.
Otherwise you may be generating phosgene gas and you'll do yourself some serious damage (like dying at the extreme end of the rainbow here) if you don't keep an outside air supply running to a contamination face mask and enviro-suit.
I'm gonna C/P this again, since it appears you didn't search for the already well-published risks and problems with heat to remove plastics::

Phosgene is an insidious poison as the odor may not be noticed and symptoms may be slow to appear.[14] Phosgene can be detected at 0.4 ppm, which is four times the Threshold Limit Value. Its high toxicity arises from the action of the phosgene on the proteins in the pulmonary alveoli, which are the site of gas exchange: their damage disrupts the blood-air barrier, causing suffocation. It reacts with the amines of the proteins, causing crosslinking via formation of urea-like linkages, in accord with the reactions discussed above. Phosgene detection badges are worn by those at risk of exposure.[3]
