73 Duster Restoration

I thought I would have the car in its last coat of primer today but while blocking the last panel I hit bare metal and couldnt feather the epoxy primer out. I tried to DA in to in area were it would feather with no luck. Grabbed a razor and scraped 3 coats of 2K and the epoxy of in sheets. Then I notice the edge of the door is the same way so I have at least 2 panels to strip to metal and start over.

Now Im worry about the rest of the car. Ive cut through plenty of other spots and dont see an issue but Im still worried about paint falling of the car. I think Im going to fix the 2 panels, Spray the last of the primer on it and let it sit till spring. If it all falls off over the winter I'll know I need to start over.

I certainly cant afford to do it all again this year.
