I've Dura Coated 4 pistols and 3 lever action rifles so far. I would suggest that you wear a respiritor as opposed to a dust mask this stuff is nasty when airborne. My wife said it skunked up the whole house and I was spraying in the garage with interior door closed. But I have a request for coating service pistols for some officers and rifles for a hunter currently. I recommend a disscant filter on the outlet of the aircompressor. the key is prepartion. I will also give you a nugget if you want retain the orginal color on a trigger or loading ramp ,etc. Don't use masking tape. Teflon tape is the ticket! WaffenAlaskan
