My RWS 48 developed cosmetic scratches on the exposed part of the compression tube early on. I have a replacement tube which I was going to put in this winter, with also trying to fix why it got galled in the first place. Wondered if GunKote would be a way to surface the tube make it slipperier in action and maybe to take out a little looseness in it's fit as it slides. Anyone has used GunKote on a sliding airgun part like this?
GunKote is a molybdenum disulfide low-friction high-temperature coating, goes on as a thin liquid, dries then gets baked-on. Is solvent and oil-proof. Can be applied over and over to build-up thickness. I've used it on four and two stroke piston skirts, inside exhaust headers (insulates inside of headers to keep the outside chrome from overheating and overbluing) but never on an airgun.
Was going to use GunKote on the metal sear and trigger contact points (internal parts) for another airgun coming my way, but didn't know if this would work on a major piece like the 48's sliding compression tube.
Figured to buff tube's factory polishing and the factory paint at rear of tube, apply this coat by coat with test fitting at each coat. I'll plug the port to prevent coating getting in there and from affecting port's fit over chamber. Will be dark gray versus the exposed metal, and will polish to semigloss.
