'68 Coronet R/T
Oldtimer
I use the Lord Fusor seam sealer and panel adhesive when needed. I will check into this. Thank you.About 2 decades ago I used some urethane sealer (for windshields) between a new door skin and the inner crash bar. The sealer shrunk and pulled
little divots all across the new door skin. I think 3M and Lord Fusor have flexible foam products just for this application.
