rust free you say ?  Group: Members Posts: 16,375 Joined: 7-January 05 From: richmond, Va. Member No.: 3,419 Region Association: None  |
I have to make a custom bumper for a car. I am familiar with the mold process but what I do not know is what type of expandable foam I should buy. I am planning to make a wooden box ( form) to pour the foam in, then attatch it to the car and start cutting and sanding to get the desired shape. What I need is something that will expand and still be closed cell enough to handle cutting, sanding and shaping, then can handle bondo being applied to get that oh so smooth ready to be painted, finished buck.

Florist foam, the green stuff, holds up to "some" resins, but not all.
Some of the epoxy resins will eat up that type of foam also. Still, the cheapest way to go is pink foam for major build, spray foam for the cracks...smooth it all out and use plaster to cover the whole thing and smooth it out perfect. try this place. www.foamation.com rich |
