View Full Version : Body work: sculpting foam

pretty crazy stuff, but I came across what seems to be foam that can be applied to anything in particular if you want to come up with an original body part (fenders, bumpers ect). Anyhow this foam can be applied by buying a bottle of this stuff. I guess the foam can be sanded and shaped like standard body filler. Anyhow I'm assuming from the pictures below that you add fiberglass to the foam once you've achieved your desired shape of your own body panel.

Anyhow can anyone point me in the direction of where to get this from and any other useful info. Thanks in advance

Looks like standard fill foam, available at your local hardware store. also available in two nifty colors! red-orangey crap, or white foamy crap.

It looks like a big mess.

DON'T use fill foam!!!!!!

It only really cures on the surface and down deep, it remains a sticky mess.

What you need is a two-part polyurethane foam that expands when one mixes it together if that's what you're looking to do.

Seriously, I would just use white foam or the blue insulation foam. That's what the aircraft guys use.

wouldnt the round yet rough surface act kind of like that of a golf ball?

i was kidding btw...but wait..didnt the divits in the golf ball make it create less air drag, and allowed it to fly straighter?

the divots create surface turbulence, to break the boundary layer flow. If the ball was smooth, a boundary layer would form that would create a vortex behind the ball and create a lot of drag. The divots create turbulent airflow that, although technically has more drag on the surface, has significantly less total drag as there's no vortex behind the ball

Yep, you can never know enough about golf balls.

Stanley makes a tool called a SureForm which is like a cheese grater attached to a plane body. That is the shaping tool you need.

some foams melt when the resin touches it making the foam pointless. i tryed some of that yellow crap and tats what it did, and i also tryed the pink house insalation foam for making gauge pods ect..

With foam like that or styrofoam, you have to use epoxy resin with the fiberglass, not polyester resin.

I think IPD sells epoxy resin

So I basically need to go spray the front of my car with gooey foam.


It looks like the car is vomiting...

There seems to be some misinformation about foam/resin compatibility here.

Epoxy resin works with all foams.

Polyester resin will dissolve expanded polyethylene (think beer cooler) foam, as well as the extruded polyethylene (think pink of light-blue house insulation). Polyester resin can be used without problems with polyurethane foam. I believe that junk in a can is a form of polyurethane.

One caveat of working with foams is that one must NEVER use a hot wire, or other heated means of working with polyurethane. It produces extremely toxic gases when it is melted. Polyethylene foams can be cut safely in a well-ventilated area safely with the hot wire, or other heating methods.

That made no sense... you just said that you should NEVER cut it with a hot wire... then said it was perfectly fine in a well-ventilated area.

Which is it? Or do you just mean never cut with a hot wire in a poorly-ventilated area?

read again, difference between polyurethane and polyethylene

It also releases toxic gasses while curing (polyurethane foams), these are diisocyanates and they can lead to what is known as work related asthma and diminished lung function. Always use in well ventilated area never melt. And never use a can of Great-Stuff for such purposes as it can release more than intended MDI (monomethyl diisocyanate). Bhopal was Methyl diisocyanate, but that is far more toxic.
