[QUOTE="ICANHITHIMMAN, post: 699829, member: 10414"] Got an air compressor? I just built my first 1911, finished it in ceracoat(similar cure procedure) came out great. I got a blasting cabinet from tractor supply(gun was included) 99$(harbor freight has them for less or so I have heard). Aluminum oxide or garnet sand is a must as you want to etch the metal. I got 50 lbs of aluminum oxide at Grangers near my house. It cost about 80$ but with the cabinet all set up its reusable. I also used max psi in my cabinet about 120 psi. Another option is a small hobby gun from woodworkers warehouse or harbor freight they are about the size of a airbrush and come with a small amount of aluminum oxide media(but its not really enough to do one 1911). You want clean media (no oil) but the dura coat will come right off. Any industrial supply place should have what you need as far as media tractor supply may as well along with automotive refinishing shops. I have 3 sand blasters now (thats what you get when you try to cut corners) all a direct result of being cheep and not just starting out with the cabinet. You can always build your cabinet from ply wood and glass. A gun is very cheep less than 20$. Make sure you soak your parts in acetone for at least 10 min and let them air dry, then preheat in oven for 30 min at 250 degrees to drive out any oil, if oil was driven out re clean and re heat before you paint.
