Okay, so I know you guys of AR15.com are the masters of duracoating so I came to you for advice. I recently got a savage axis bolt action 270 win. I am working toward duracoating it. I already purchased a "touch up spray gun" from Harbor freight and so now i just need the paint. I have chosen to mask tiger stripes on the black barrel and stock and go over it with Magpul Foliage Green, but this has posed a few questions though.
-What can I use to mask the pattern before i sand it so that will not rub off from the sanding? Will painters tape hold up to the sand paper? -220 grit is what i should use on my synthetic stock and scope right? -Can i run my spray gun on my 150 psi compressor even if the gun recommends 40-60psi with a maximum of 120psi? |

Put the touch up gun down and step back! I just completed duracoating 300 AR magazines for work. If your working large area surfaces, do yourself a favor and go to Menards and get the HVLP spray gun kit. I just got one for $25 on sale. PRACTICE! PRACTICE! PRACTICE! Use a cheap quart of automotive paint to PRACTICE! I used the blue painters tape to mask and sanded the mags with 600 grit and had no issues. Your compressor should have a regulator on it, if it doesn't....then get one.
I can't recommend enough to test spray or practice on something until you see and get used to what is going to happen. And if you get the HVLP gun from Menard's.....don't expect to mix paint in the cup. (lesson learned), the hardener will sink right to the bottom and part of your project will be shiney and part of it will be as it is suppossed to be. |

Not sure which touch up gun you have, but it will probably work just fine. I just painted one with an airbrush, so I don't see why it wouldn't work. I found that using their reducer and retarder helped me get a nicer finish.
I agree with the guy who told you to practice using a cheaper paint until you get a look you like. Automotive paint isn't cheap, but fucking up a gun isn't either. Practicing with spray cans would probably do just as well in figuring out your pattern. ETA.....220 is probably a bit coarse. I would use 600 or 400. Yes you can use your compressor. Just dial down the regulator. I also used a dial valve and guage at the gun along with an in-line dryer to remove the water from the lines. |
