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.

Use polyurethane two-part foam, The foam from diy shops is rubbish for your purpose - it leaves big holes as it expands.
