I am looking for some input on rifle finishes. I have used Dura-coat on my M40-A1 and was not overly impressed. I just used the Matte black from one of there cheap air brush kits. There are several scratches down to bare metal and the finish did not seem as good as advertised. I would need something DIY but it needs to last since it is going on an EDM windrunner which is not cheap. Any input would be greatly appreciated.
