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: https://www.lbifiberglass.com/
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.
 
I'll use Miller Stevens MS122 when I want a spray, MS143 for brush on, and Dow Corning 7 when i want a thick coat.
