the duracoat seems to be holding up. it's a preban oly lower that had bare aluminum showing when i got it. $45 to refinish. i've put around 700rds though it and don't notice any wear at all. it's black as night too. IMHO it's more durable than the dpms teflon.

Good to hear. I have two uppers that I want to refinish to match the preban Colt grey. I spoke with Steve Lauer at the Shot Show and the NRA show in Orlando and he said it was as easy to do as spray painting. They sell the degreaser -just break it down, degrease, spray it on, heat it a little if you want it to cure faster, or let it dry at normal temp and it takes a couple of weeks to fully cure.
What Steve told me about Norrell's is this: if you don't heat it enough it doesn't cure hard enough and scratches easily (sounds like what happened to yours); if you heat it just right it is a good finish; if you heat it too much it gets too hard and brittle and can "break off" or something to that effect.
What he said is so good about his Duracoat is that it cures without heat. It just takes longer.
