All,

I would like to permanently remove the wrap-around bump strip from my W123, plug the holes and repaint the car.

What would be the best way to plug these holes? When I clean them up with a steel brush and then apply bondo (with fiberglass strands), the bondo just drips off or falls through the holes. I've been thinking about trying to cover the holes on the inside with fiberglass cloth and then applying bondo. But I haven't figured-out the best way to stick the cloth to the inside of the holes when I can't always get to the inside surface.

I know, strange question, but I'm sure someone has done this.

I've always used a two component filler that is strong enough to take threads. This usually worked for small holes.

Never use bondo on any repairs. It is too hydroscopic to hold over the long term.

Now on what to use: I am outdated when it comes to what is available out there. I used to use a product called "All Metal" from USG. There may be something better out there now. I'd ask of who is currently doing bodywork.
