    Default Anyone try 3M bondo on bumpers?

    I just picked up my GT last week and knew it had a few issues 1 being that it had a cracked front bumper

    I got some 3M bondo and surprisingly its holding...

    Has anyone else tried this?

    I will pull the bumper skin and use the mesh supplied with the bondo and reinforce the back.

    I will sand it down and just use the rolled masking tape method to blend the paint.

    You need to use the correct products for the plastic or it'll crack again. You can do a skim coat of body filler on it after you've gotten it 99% there with correct product.

    Chewy you were right!...it held overnight and then when I got in the sun midway through the day it cracked again...

    A used bumper skin it is!

    maybe I can find one in gray.
