Any one know where I might find big blocks of styrofoam I can use to shape pices for custom side skirts and door pannels? Id liek to work with pices 2' 1/2" X 2' 1/2"x 2' 1/2" or bigger. like I said I need big pices, and they need to be able to be sandable without tearing. If no one knows where to get them then info on what type of sandable perticularly dense foam I should look for.

 

we had to make some fenders fit a buddy's car when he went wide body. we picked up some blue foam blocks from lowes and they worked well enough to give us the general shape them glassed over them hallowed out the back side and added body filler to finalize the shape. i don't remember the density rating or any of that but at least you might be able to get a direction to look

 

You can also get some quality foam stuffs at any arts and crafts stores. They come pretty cheap sometimes if you know where to look.

Sometimes if the parts aren't that big I believe using some aluminum foil will work too (if you're fiberglassing).


Always make sure to coat that stuff good, bondo, and sand sand sand!
