Bondo on plastic bumpers?

Is Bondo going to be flexible enough to stick to my plastic bumpers? '98 Volvo S70. I've got them off the car, so most of the flexing will be when reinstalling. I need to fill some heavy scratches and so on.

not sure about Bondo but Evercoat does.

Welcome back
I have used bondo on 3 bumpers before with no problem but they make special stuff for them now but I don't know the name of it. Also I did not use a flex agent in the paint for the bumpers either. My paint guy told me I didn't need any and there was no problem for me but your mileage may very. Actually I didn't have to flex the bumpers hardly at all when reinstalling them.

it also depends on what the bumper is made of - you can tell by the backside - theres a triangle with the info there..

Thanks! Now I'll figure out if I just want to go with what I have, or make the trip to town for the special stuff

some plastic you can 'weld'
some you can get fillers for

You can repair just about any kind of plastic - its just a matter of figuring out what to use

I got lazy & went with what I had on hand, "3M Lightweight Body Filler" -- and it seems fine, as far as sticking and so on.

I just put some regular old bondo on a 2 year old scratched Mustang bumper for a friend . Went on fine and sanded and primered good. Next week he will paint it so I will hear if the bondo stayed on then.
