i got the m-power bumper and it has two big wholes in the back. i need to know what i can use to put some grills back there. i got my grills that im goin to put on the back i just need to know what i can use to glue them on there. i may use bondo but i dont know. can some one please help me.

 

Bondo works for almost anything O_o
as long as it isn't for the outside...its not exactly the most appealing

 

I've got to put a grill in the body kit I bought, both skirts, rear bumper and front, I'm thinking about using angel hair (its a fiberglass filler) to bond some bolts that I've welded washers to, to the kit, so later if I want I can swap grills easily or add lights
