i have a crease in my rear bumper. its shaped like a triangle and dips in the middle.

i heard about the heat gun tactic. and pushing it out.

but what can i use to help fill in the dip in the middle.

i have metal glaze but i heard that it will crack once the bumper flexes.

and it doesn't adhere good because its plastic.

any ideas???

its a edm rear bumper and its hard for me to find a new one.

 

Work the plastic the best you can before you glaze so you only need a thin skim coat. If your going all out, use a good high build primer and add a flex agent in what ever paint/primer products accept it, and use raw plastic adhesion promoter before the primer.

The above mentioned product works well...

U-POL's 706 works really well on plastic too, though it should be a bit cheaper.

 

thanks for all your help!
