Foam for custom body work?
Does anyone have experience using foam for custom body work?
I want to fabricate the middle portion of a fiberglass bumper. (the shape isn't super complicated)
I was thinking about getting the foam in there, sanding it to the shape that I want, then laying the fiberglass on top of that to get the shape permanent. Then just flip it over, knock out the foam, and re-enforce with more fiberglass.
I found a two part expanding foam I think I might get. Is it worth the money besides that "great stuff" foam? I'm just gonna rip it out after i get the general shape?
