Paint Removal

[CC Rider]

Now that it is blazing hot here, it's time to begin summer projects on our cars. The previous owner of my '66 painted all of the metal interior trim around the Windows and windshield. I doubt they were black from Chevrolet in 1966.

My plan is to remove each assembly, remove the paint, and polish the surface. If he used the same paint that I removed from the bottom of the rocker moldings, paint removal will be a challenge. I used leftover stripper from Home Depot, and that stuff struggled. Maybe it sat on the shelf too long. Lacquer thinner was ineffective.

What would be the best stuff to use for paint removal from the interior trim?

Thanks
