RE: Sanding / filling / polishing tricks

TT2, I rarely glass my molds anymore. I use 6 lb. urethane foam and Duratech that right out to the finished shape. The Duratech acts like a skin and works fine. On another note: I used PVA several...

RE: help with sandwich construction

RE: RE: Epoxy Resin

I have to add my two cents worth. Yes using heat dramatically speeds up the cure. However be very careful with the amount of heat used, especially on a non-bagged part. Excess heat will cause the...

RE: High temperature Carbon

Phenolic resin will take 900 degrees and is cheap. It works like epoxy or polyester. My problem has been getting someone to sell less than a 55gal drum of it to me.

RE: How to clean PVA out of spray gun

205 epoxy cure time

Theo, I would venture to say that NO epoxy resin will be completely "dry" in 4 hrs at room temp. Some will not cure properly at 55 F, others just take longer at lower temps. It may have cured in the...
