Title: Bondo Removal
Post by: 72vwtype2 on February 08, 2006, 08:26:31 PM

I am about to start working on my engine deck lid and a fender. They both have a moderate amount of bondo on them. I believe once I remove the existing bondo I can smooth out the metal and use considerably less bondo. My questions are:

What is the best way to remove Bondo? Heat (Propane Torch), Sanding it out, Chemical (Aircraft) or Sand Blast?

Then once the bondo is removed, and before working the metal, should the bare metal be protected, such as etch primer?

Thanks.

The last time I had to do it I got good results with Canadian Tire house-brand chemical stripper. It took at most two applications and some scraping to remove up to 1/4\" thick. A quick once-over with a wire brush to clean up and it looked like virgin metal.

I like using a bondo buster or an angle sander. CAREFULL AROUND EDGES. If there is a fair amount of rust repair to be done, use an corrosion resistant etch primer then use DP 90 epoxy primer. Then put filler on that. If you need any more hints or guidance, pm me and I'll give you what I know

I just used a wire wheel on my drill. Made a huge mess but worked great!
