You know I don't know why I pulled the gas tube, I suppose I certainly could've taped it easily enough. I guess I just thought it would be easier to get it out of the way. Geez, I thought I was lazy enough with the lack of preparation I already did, you're right-I could've just taped it!
BTW, just to be certain I performed the test after baking, and wiped the finish with MEK, and the Norrell's stayed put, not even a bit of color came off. For grins I also had an FN 30-round mag just laying on my workbench, when I was done with the AR I looked over and grabbed the mag, pulled the follower/spring, sprayed a shitload of brake cleaner and wiped it off. Shot the thing as well, tossed it in the oven with the AR and took it out an hour later. Guess what? Another use for Norrell's...what a beautiful magazine. Loaded and unloaded the thing from the M4gery's magwell a bunch, and no scratches seen or other blemishes, it seems to hold up well. Gonna do a bunch more mags now...
As far as the equipment, I had an old Binks detailing gun (external siphon mix), hooked it up to my compressor @ about 18-20psi through the external regulator, which atomized the Norrell's just fine. I'm gonna mess with the pressure a bit more to get just the right amount without using too much paint. Any suggestions would be welcomed by any of you guys who do a lot of that sort of thing.
I'll post pics as soon as I can.
