Release agent..


Garage hack at night.....
What is the best release agent you guys have used? I am building a plug to make some tubes and after the plug is all painted i just want to wrap 2 layers of fiberglass over it, let it cure and pull off the painted plug.

Basically what I am making is a plug for these blower/turbo tubes. I'm tired of making them by scratch every time I need one. So I am making a one size fits all and Ill just modify accordingly to whatever project I am working on.



I have only molded a few parts but used PVA release agent from this place:
They have mold release wax also.
I have also used the PVA to coat and seal the final coat of laminating resin so the surface can cure, otherwise it remains sticky. It washes off easy with water.
