company that offered solutions to several problems. Let me first cover the problems I hoped both products would solve. I, like many of you, hunt in the
T
north. For me that is northern Wis- consin.
As you know, rust from frost
is a problem that can develop when you have changes in temperature and humidity. Such as when you bring your gun in from -10 to +68. What you really get is sheet ice on and in your barrel and action. Not desirable! One thing that helps is leaving the gun in an unheated area rather than bringing the gun inside. Sooner or later, though, you want to bring the gun inside. Also, we all deal with rain, and as
we all know even stainless steel rusts. Another example: I wrap my guns in camo tape and my concern is rust form- ing between the steel and the tape. This product is a moisture barrier so I don’t have to worry about moisture between the tape and steel. One final problem to be solved
is rust during storage. I struggle with keeping my guns rust free in my safe. I am always recoating my guns with one product or another. I had heard of a company called
Dynamic Coatings, Inc. This company offers products that tests show prevent rust on treated parts. They offer two products I was interested in. One, Dyna Shield, is for the exterior of a firearm. The other, Dyna Tek Bore Coating, is for use in the bore itself. Yes, several companies offer bake-on coatings in various colors. What I find with the Dyna Tek Coatings products is that they are easy to use, clear, and are not a bake-on product. Once applied, you can’t tell they are on the gun. Just a note here: I am using it on guns but it can be applied on any number of materials needing protection from the elements. One additional important benefit
of Dyna Tek’s Bore Coat treatment is that it dramatically reduces barrel foul- ing and reduces cleaning time. More

he following is a report on two products by the same
about this product shortly. I wanted to test the claims so here
is what I did. I took two rifles, one a blued Savage and the other a stainless Sako (ouch). I removed the guns from the stocks and in a very inconspicuous place put a 1-inch square of cotton cloth soaked in salt water, covered them with plastic to keep them wet, and waited. I waited until the cloth showed
the first hint of orange/rust. In the case of the Savage that was 26 hours and 20 minutes. Being stainless, the Sako took longer, as you would hope. That was three days and 12 hours. I cleaned the guns and applied a strong preserva- tive onto them in order to ensure I was beginning from a normal condition and started over. I followed the easy directions ex-
actly. They were (in brief): degrease and clean the steel and rub down the area with rubbing alcohol twice (alcohol included). They make it clear that you must get even the pores dry and bare. Next apply a small amount of Dyna Tek Dyna Shield to a cotton cloth, wipe the area to get it evenly wet with Dyna Shield, let soak in, and dry about 20 minutes. Repeat three times. The idea is this soaks into the pores of the steel and builds up and slickens up. That’s it. I could not tell any change in color compared to the untreated area. Dyna Shield does have UV blockers in it so I would think guns like the Ruger where the action turned plum on some guns in the past may not do that on yours. I repeated the salt water test with
the same sample solution and waited and waited and waited some more. I gave up after five days. I wanted my guns back in action. Cost is $9.95 and should do one
long gun. I will be treating other guns over time, plus I won’t have to worry about the guns rusting in the safe any- more. Again, you can use this on even the insides of gun parts except in the barrel. I will cover the barrel next. I am not certain about abrasion
resistance. I suspect since this is a cer- amic type coating it should be durable. Besides, unlike bake-on colored coat-
ings to recoat or touch up is a matter of degrease and reapply. There is no concern about blending the touch up with the original coat. Lately, I have started to do some
defensive shooting/training and found the Kydex holsters tend to be hard on handgun coatings. This got me think- ing about the Dyna Shield so I gave it a shot. So far it hasn’t worn through. But again if it does it is easy to touch up. One note: the pistol I applied it to had one of the black, slightly rough to the touch, coatings on it so the first two coats of Dyna Shield looked a bit streaky. However, the third coat evened out and made gun look and feel much nicer. The second product from Dy-
namic Finishes I tested is for inside the bore. This product is ceramic in nature and again requires no heat and is a permanent treatment. The claims are that the coating will rustproof your bore. You will be able to fire more shots between cleanings. The cleaning process will be
easier by virtually eliminating bore scrubbing. The company does not claim the
product will shrink group size or boost velocities. When I first heard about this
product I thought if it worked it could really help me enjoy shooting more. The worst part of range day or prairie dog shooting was cleaning the bore. I like to clean about every 50 rounds when shooting prairie dogs and maybe 40 shots for range testing … if I can get away with it, that is. The chance to avoid going through
all those brushes and all the different solvents and patches is just too hard to pass up. Also, keep in mind my prob- lem of moisture control in the winter. I would feel much better knowing that the inside of my barrel is protected. I thought at this point some skep-
ticism was in order. Will the product do what it says? Will it be safe in my bore? And, what will it do to my accuracy? That was the point of the test.
