[QUOTE="Forester, post: 461367, member: 11102"] Well I bit the bullet Saturday and after practicing on some scrap material I blasted my 7-300WSM with 120grit aluminum oxide. and then duracoated it. Blasting went well, and I was able to get a very nice, consistent finish across the various parts. I did have to work very, very slow so that my air compressor could keep up. I did hit the internal temp shutoff on it once while blasting leading to an hour wait to start again. A bigger compressor is on the shopping list now, just need to liberate some funds from other priorities sometime. For the duracoat part, I could not be more pleased. I rigged up a paint cabinet of sorts in my shop with a tarp and box fan. It worked well and kept the dust out and mess in. I degreased with trustrip, blasted with Al. Oxide, and painted with an HVLP spray gun from Harbor Freight. The spray gun has a 1.0mm nozzle which is on the large end of what Lauer recommends but with the material adjustment knob turned down I had no problem avoiding runs and the over-spray was very minimal. I coated with combat black and then used the duraclear over top. All in all things turned out as good or better than I hoped for. The parts are now in my safe curing as I will not need this rifle for awhile so I will let it set up for a week or two before I fool with it much. Actually I am waiting on a Manners stock that wont be here until March so the gun wont get any use until then. [/QUOTE]
