Removing Bondo From Bumper?

[Blurred Talon]

I picked up a 2GB Talon bumper for my car and I'm getting ready to paint it.
However the previous owner filled in the where the Emblem goes and I want to have them emblem there.

I've already started chipping it out but I'm wondering if there's something else I can do.

propane torches work great on sheetmetal bondo, i woudnt try it on a plastic bumper. pull the bumper and hit it from the rear with a ball peen hammer. not too hard, and the colder the better. it should pop out.

I think he means the warmer the better. The colder it gets, the more prone to cracking it becomes. When it is warm, it is softer and will allow it to flex more.

Chisel what you can and then have fun on the detail work. PIA i'm afraid

Yea I decided to hell with it and I'm leaving it filled.

Why don't you take it to your local paint shop see if they can do something about it?

Not much they can do. Any solvents will hurt the bumper so it's just tedious work.

Die grinder with sanding pad is best. Just don't cut into the plastic to much.

I don't really feel like spending the money to be honest.

Not sure what It looks like but could you cut the whole center out?

nope, colder, specifically the bondo as it will crack easier. even at 30 degrees Fahrenheit, he would have to really try to hurt the plastic bumper.

also, solvents generaly dont harm bumpers these days, but the bondo wont be affected by them either...

Then I couldn't rock the Eagle emblem.

listen i paint at my house take you some paint stripper for plastic and it will pull the bondo off. Or you could take some lacquer thinner and a rag and rub it off and it wont hurt the bumper.

Trade me bumpers I want mine shaved like gofers

 

[zxrider_sa]

Colder is correct. You want it to be brittle and break and chip. Not bend and flex. But just sanding it out with a air powered die grinder is the best way to go. I have done paint and body work for the past 6 years and that's how I do it.

Update for this, I used adhesive backed sanding pads, 40 and 80 grit with an attachment for my drill and powered right through all of that bondo in no time.

Nice, just be sure to finish in a higher grit like 180 if you priming so the scratches dont show, and if your aren't priming (you should) and just sealing,basing,clearing than finish in 400-600 (600 if just basing and clearing)

I still need to do some flexable filler where the pads dug in a bit deep then I'm moving on to blocking and primer.

I love collateral damage...It seems anything I do results in at least a little....

Which leads me to a lesson I take into consideration heavily (although too late since you already un-shaved it) "If it's not broke don't fix it." Or pay someone else to fix it so when they screw up they can fix their mistake too.. haha

 

[Blurred Talon]

Yea but then I wouldn't learn new things and I'd be out more money, where's the fun in that?

 

[DaRKSiDeGSX]

true true....

I'm like Herman Munster any bolt I turn snaps, I gouge the shit out of anything I sand.... haha

I try to fix things or improve them and usually end up frustrated...

The catch 22 of project vehicles...

Yeah I was going to say some sanding discs will eat through bondo like a fat kid through cake. Once it starts getting thin just switch to 300 or higher.
