Just go to Home Depot or Lowes and get insulation foam.  Pink at the Depot or blue at Lowes.  You get a hell of lot more for the price, and it sculpts better.  No need to go to a specialty industrial place and its much better than florist foam. Oftentimes, strand works better for complex shapes, especially when working over a buck, ie a mold (which is what the foam is).  You can also thin coat the surface of the foam with joint compound and sand it super smooth so you have a perfect surface.

Well that's an idea!  I'm going to have to try that sometime!

If you want something that acts similarly, but is much stronger, there is a material called Aqua-resin.  It's a very opaque plaster-like material that gets very hard and has a similar cured hardness to fiberglass resin.  I've been using it to make castable positives for years.  It's nice because of it's hardness and zero toxicity.  Here's an example of a master made from insulation foam and Aqua-resin...

What is the favorite for a release agent on molds when doing fiberglass?

Yeah the wax is a must. fills small holes in really well. I have been spraying PVA over that but any sulfur free mold release will work like what IRK posted. I have used straight up axle grease in the past with good, albeit messy, results.

Snapshot of what I got done today.  Body filler is still in progress for the seat, it's pretty ugly at this point but I think it'll look fine when I'm done.  The seat pan is done and I'm happy with the mounting setup too.  Battery and electronics tray done.  I got the frame braces done tonight but there is still some cleanup I need to do.  My welding skills still need alot of practice and even my grinding could use some work but I'm happy with the progress.
