Stop in for a cup of coffee

soo... i'm itching to get my car going now before summer is gone.. (although i like winter driving better anyway... as long as no snow) I am planning to strip the fenders to metal>primer>paint.. they are in epoxy primer now but i have no idea whats under that... could be 4 layers.

Question is though... best way to hold them while working on them... mount on the car temporarily? 62 fenders are pretty big and i can just see them flopping around on a table or buck while trying to work
Something like this. I sold a bunch of them. 1721740832851.png
