Removing Bondo.
Is there anything out there that could soften Bondo (or whatever it is). I have 1/8" thick stuff on a very thin and rusty back window panel from my Special Coupe. Some of it pops off easily, but some is really stuck. I'm hoping to clean the piece off, use paint remover, and then sand it to prep for primer.

Re: Removing Bondo.
While paint remover will attack plastic body fillers, try using a heat gun first to see if it will release.

Re: Removing Bondo.
I've used a silicon carbide disc on my grinder. I LOVE these things. Like this one:

Re: Removing Bondo.
Heat the bondo with a propane torch and it will fall off.

Re: Removing Bondo.
Never tried heat, I assume the heat gun wont warp the metal. I have used paint stripper, let it soak in for a bit and it comes off fairly easy. If its thick will take several coats. In the past I got the stripper from HD, got the best they had cant remember the name off hand.

Propane torch is the way to go.

Re: Removing Bondo.
X3 on propane torch. Heat a small section (on the underside if accessible) just enough so that it peels off with a putty knife. Move to another section some distance away. Keep feeling the panel with your hand so it doesn't get too hot. This is what I did with zero panel warpage.

Re: Removing Bondo.
I’d worry about warpage with a torch
Heat gun generally won’t get hot enough to warp But experience and skill would preclude likely |

Twisted knot stiff wire wheel on a grinder does good and won't bother good metal
