What is exactly is pollycrlic or PolyC? Is this water, oil or lacquer/dope based?
It is Minwax Polycrylic. It is a water based urethane. You can glass with it or use it to fill the weave of fabric. It is a bit thick right out of the can and I thin it about 15% with water. It has little to no smell and cleans up with water. It does not get as hard as fiberglass resin but remains somewhat plyable. It dries fairly quick depending on temp and humidity. It will accept virtually any paint. I do prefer to apply a primer coat before painting but it is mostly to get a even base color before the color coats go down.
You can get it at your local home improvement store for approx. $15 a quart. I prfer using foam brushes to apply the liquid PolyC. You can also get it in spray cans for $10 a pop and use fro a clear coat. It is gas resistant but not nitro.
Hope this helps!!
