Spray-On Finish 'How-To' Videos
In recent years, spray-on finishes have become a popular alternative to traditional blueing for chrome-moly barrels and receivers, plus other gun parts. Spray-on finishes provide excellent rust-proofing, some degree of abrasion resistance, and many of the finishes also provide increased lubricity for moving parts. (Be aware, however, that these finishes go on thin, and the finish can wear through on high-abrasion areas, such as slide rails on pistols.)
Matte spray-on products work well for hunters looking for a dull, non-glossy finish that blends into the background. A bake-on polymer-type finish is a very good choice for a shotgun or rifle used in the winter or in damp environments (such as duck blinds).
Brownells has created a Six-part series of videos that explain, step by step, how to apply a spray-on finish to gun parts. In Parts I & II, Brownells gunsmith Dave Bennetts explains the basics of spray-on finishes, then shows how to properly prep metal parts for finishing.
In the next four videos, Bennetts provides specific application instructions for four different spray-on gun finish products. Bennetts explains the strengths and weaknesses of each product for particular firearm types. Click the links below to watch the specific product videos:

Spray-on Finish – Chapter 4 – Gun-Kote
Spray-on Finish – Chapter 5 – Teflon-Moly
Spray-on Finish – Chapter 6 – Aluma-Hyde II
Of the four featured products, Gun-Kote, sold by Brownells under license from KG Industries, offers superior corrosion resistance, and is probably the most popular of the four products for use on rifles. Gun-Kote was originally developed for the military and was first used by Navy SEALS. Gun-Kote is an “oven-cure” finish applied to pre-heated metal. Though it goes on thin, Gun Kote cures to a hard coating that resists abrasion and won’t wear through as easily as bluing or chemically blackened surface treatments. Brownells Gun-Kote is offered in a wide variety of colors, shown below.
