Removing old bondo

I have a modified 50 Hudson that has bondo on a door panel that is cracked and needs to removed. I have had two suggestions on how to remove the bondo. One was to use heat from a propane torch to gentle heat and scrape off the old filler. They stated to be careful and not get the door real hot as it will cause a warping problem. The other suggestion was to grind out the old bondo.

Would appreciate you suggestions on what would be the best way to remove the old bondo.

Wear a good resiprator and grind it out with some 36 grit..should not take all that long...That torch idea does not sound all that good to me..

a wire wheel will do a nice job and not generate too much heat.

the propane torch works great. you don't heat the bondo. one pass over it and it will turn to dust. i use a welders brush to remove it. fast and a lot cleaner than grinding. the torch pulls the solvent out and leaves it dry and brittle. give it a try.

A muffler gun with a blunt chisel, turn the air pressure down a little, it will take it off fast with out denting it if you take it easy.
