i have a Urethane rksport front bumper and it has a crack in the bottom of it, can i use fiberglass or bondo to fix it then paint it or is there special urethane stuff?


steveo

fiberglass wont work. they do make something specially for urethane to fix. check out and auto store and ask them.

Think about it...

urethane flexes...

fiberglass and bondo... do not (well a little, but not much at all)

If you put something that doesn't flex on something that does... it's going to crack.

They make special stuff for urethane repair.

I use Speedgrip usually.

i would check what type of plastic you are goin to be working with first off
then you go from there
is it polyurathene?? is it tpo or tpe or pp
if ya look on the inside of the plastic it should say if it does not here is a little tip that will help you determain what type of plastic you are goin to be working with
cut off a small piece of the plastic on the inside of it or somewhere the piece will not be seen and i mean a small piece
take that and put it in a glass of water
if the plastic floats you need to promote the plastic if it sinks then you can repair the plastic with out the adheshion promoter
i suggest doin that first then gget back to us

can i haz bondo
