What's the difference? I see references to blue foam all the time - why?

When people reference blue foam they're probably talking about Dow Styrofoam PI
(Pipe Insulation) or BB (Buency Billet) foam that can be hot-wired. It's about
2 lb/sq ft, pretty cheap, comes in big blocks and can be laminated over with
epoxy but not polyester or vinyl-ester.

I have the G-III fuselage "propped" up on the supports using
Styrofoam(TM) pieces. When I was working on the reinforcement rib
laminations I had to lay the stippling brush down...some where....and
I laid it on a piece of Styrofoam. It went right through the board in
less than a minute.

You're right. Vinyl ester resin and Styrofoam do not work well
together. :-))
