Great Lakes Garrison & Base

Anybody know of any places in northern Macomb/ St. Clair Counties that carry automotive bumper filler? All the stores near me (Autozone, Carquest, Advanced Auto) don't carry it. I need it to fill the gaps on my clone chest piece.

Doing a quick search this place in Macomb Twp has it.

I've never used them or heard of them, but it's a shot.

Aww, screw it. I'm just going to do the sludge method. Thanks anyways!
