I need to build a 4" curved tube for an EFI setup (on a car), so I'm using fiberglas/polyester resin.
I made a form out of a 4" foam "Noodle" float.
I'm using polyester resin to form the glass strips aound the curve. The problem is I need some kind of realease agent to protect the foam from the resin and be able to clean out the inside of the tube.
I've heard latex paint, or dipping the foam in melted parafin wax would allow the foam to be chipped out and dissolved with acetone, and the acetone would clean out the wax or paint.
Anyone have experience with these or anything else?

Thats how I did my gauge pod. Used florial foam. Covered mine with elmers clue / fiberglassed/ acetone foam out. Of coarse I had help from members here. My first glass work.

Nice Job.
BTW- using the noodle as a base form is a great idea.

VV-

You need to turn that into a business.You could make a killing just from the people on here. I'd be first in line.

Very Nice. Is the Carbon Fiber real or a sticker?

Elmers glue huh?
Sounds good, just soaking in water should clean that out.

The carbon fiber is vinyl same as boat wrap.

Thanks Chris, I had plenty of help here in fiberglass & paint.

4" noodle + hot glue gun + drywall compund (smoothing the form) + a coat of elmers glue = air tube form.
Thanks for the info all.

Regular old bondo works great at wal-mart. This is what the pod looked like before I covered it in vinyl
