First off I'd like to issue this warning: DO NOT ATTEMPT TO USE THE "CHEAPER" DURACOAT IF YOU CANNOT FOLLOW SAFETY INSTRUCTIONS. You'll need a large airspace, respirator, long sleeve shirt, pants, and eye protection. The chemicals in "Cheaper" Duracoat are no laughing matter. Saving money isn't worth the brain damage if you can't follow safety instructions.
That being said, I just spent $1.82 refinishing a 10 round magazine and had more than enough mixed coating to do a 40 round magazine. This was just a test run and how was I supposed to know 3 table spoons of paint would last that long?
What is "Cheaper" Duracoat? While sniffing chemicals and getting high, I was huffing duracoat and realized I had smelled it before. I went to the local high-on at the Sherwin-Williams dealer and he said "That's Polane S Plus Polyurethane Enamel". (I'm just kidding about the huffing part. I decided to spice up my post a little bit).
How is it "Cheaper" Duracoat? Polane S Plus Polyurethane Enamel is chemical resistant and the black color can resist temperatures up to 500 deg F (That's SW's stated value, obviously there's a factor of safety in there).
You still haven't mentioned the cheaper part!: Duracoat in its cheapest form is $320 for 128 fl-oz of Duracoat and hardener. 128 fl-oz of Polane S Plus Polyurethane + Catalyst + thinner + tax was $155. (NOTE: I mean cheapest "per unit of volume. You can buy duracoat in smaller containers)
