Roof to quarter seam?

[moparvinson]

What is best for roof to quarter seam on a 71 charger? They used bondo before I got it and it just keeps cracking. My first car was a 68 charger that was same f3 medium green but had a green vinyl top, same as the graveyard cars green 71 r/t so that might be an option. Thanks

There’s some “bondo” that has aluminum in it and is used in high stress areas.

Lead
Or I've used All-Metal filler with good results.

Best option is to cut that junk out and weld a solid filler strip in.

All metal, couldn’t remember the name.

Lead is what they used at the factory. But very toxic, by modern-day standards. Think metal. Bondo is a plastic, and may crack when hammered by 9-second quarter mile runs on the unibody.

As others have said, using various metal (kee non-cracking) solutions is what many find to work best, long term.

Alternatively, if you're flipping it, and selling it shortly after paint, go with Bondo.
