I don't know if this is useful information for this thread or not, but mixing cerakote in small batches becomes a heck of alot easier if you just buy some empty syringes to meter both parts. It's more accurate, you can mix it right in the cup, and you don't waste much. It's a forgiving coating to spray, and I like the full cure in two hours.
I think Durakote is excellent for stocks and very tough. I wish they would sell a thicker version so us low volume types could blow webbing without the expense of Polane. One note on Durakote is that it is way tougher than most primers, especially high fill primers. If you spray it over a soft primer, you lose a lot of the benefits.
Just my opinion.
