I am working on my 87 3 door. I removed all the trim. What is a good method for filling the holes from the upper and lower trim pieces? Is there a function for those 2x4 holes in front of the rear wheel wells?

the door ding trim i assume? best way to fill 'em is welding them.. i wouldn't want to use bondo, slamming the door might be the best reason for not using it..

 

possibly fiberglassing? maybe.. still not the greatest bond but fiberglass mat on the inside of the panel with mostly resin to fill in the hole..

 

painting is required with all listed.. well to atleast look "clean"
