Frequently Asked Questions2020-01-14T22:30:25-06:00


After curing the part it was wiped down with MEK/Acetone and a small amount of color came off on the rag. Why?2020-01-14T22:19:57-06:00

Gun Kote is completely resistant to all known solvents once cured however after the initial cure some color coming off the substrate when wiped down with MEK or Acetone is normal, especially on flat colors. It is referred to as “fluff”. However if an appreciable amount of color is removed with these solvents the coating is probably not cured.

A typical reason for excessive color wiping off with solvents is usually caused by poor curing. Ovens can have cold spots that will cause incomplete curing or the way substrates are placed in the oven can cause inconstant temperatures across the substrate.

If the temperature in the oven is determined to be consistent and you’re seeing excessive color coming off the substrate when wiped down with any solvent please call our technical staff for help at 800 348 9558.

After I sprayed the coating, the finish is chipping or peeling. What happened?2020-01-14T20:59:39-06:00

Gun Kote, applied properly will not chip, crack or peel. Going back through the preparation process will usually find the issue that caused the problem. The use of Glass Bead instead of the 120 grit aluminum oxide will cause the coating to peel. Not degreasing well will also cause the coating to peel. In all cases it is something in the preparation process that has caused the problem.

When refinishing firearms we have found oil will creep from the barrel receiver and cause the coating to “lift”. To resolve this problem preheating the barrel/receiver to curing temp will leach the oil from the parts and solve some of the problem.

Do I have to preheat my parts?2018-11-16T22:01:18-06:00

No. Gun Kote does not require a heated part in order to be applied properly.  However, it does help in cold enviornments or right after degreasing, when the parts are cold.

Do I have to sand blast the parts to touch up the coating?2018-11-16T22:07:29-06:00

No. Gun Kote has excellent re-coating adhesion which simply means it will stick to itself well. To touch up an area that may have runs, lightly sand the area with #0000 Steel Wool or 600 Grit Sand Paper, Degrease, re-spray and cure. For areas that have light areas, simply degrease and re-spray.

Do you customize gun mats?2018-08-26T15:06:46-05:00

KG Industries LLC can customize several metal protection and firearm related products to meet client requirements. We can put the logo of your company or any logo of your choice on our gun cleaning mat for a more personalized item. Call us for more information about customization options and pricing.

How do I know when it’s time to replace my gun cleaning mat?2018-08-26T15:06:17-05:00

Regular use will make your KG Gun Cleaning Mat grimy. The good news is you can wash your mat to remove the grime just like other washable textile products, and you won’t need any special cleaning agents. Regular detergent can be used to clean the mat; just make sure to wash it mat before the grime gets too thick. You will know when washing is necessary when grime is starting to flake off the mat’s surface.

I degreased the part thoroughly, but it still looks like the coating has “fish eye”. Why is this happening?2018-08-26T15:05:59-05:00

Fish eyes can be caused by using poor degreasers which can leave a film reside or oil leaching from the part while curing. Water on the substrate can also cause fish eyes and finally oil in the air lines can cause this problem. In all cases fish eyes are caused by contamination.

I keep getting runs in the finish, what can I do to fix this?2018-08-26T15:05:46-05:00

Runs are most commonly caused by too much material being applied onto the substrate in too little time. This can be fixed by turning down the material flow and/or pre-heating the parts or both.

I tried to touch up my part after I cured it and the area I re-sprayed came out different than the rest of the part.2018-08-26T15:05:34-05:00

Part temperature, spray gun distance, air pressure, properly mixed material and light source are all variables that could cause a change in the coating appearance. Making sure the substrate was spayed in the same way as the initial coat will help resolve this issue.

The coating seems to be translucent even though I have sprayed multiple layers. What is going on?2018-08-26T15:05:19-05:00

A translucent appearance is caused because the solids have not been properly reconstituted into the coating before spraying. Thin Film Coatings are low in solids and when allowed to sit for any period of time the solids will settle to the bottom. Not mixing well will result in spraying mostly colored solvent and produce a translucent look. Shake the can for a few more minutes and re-spray the parts.

The coating should have come out flat but came out shiny instead. Why?2018-08-26T15:05:07-05:00

There are two reasons for flats and satin coatings to come out too shinny or Flat coatings to not look flat enough. Thin film coatings in general will look different if sprayed on a cool surface as opposed to spraying on a warmed surface. Thin film coatings will also look different if sprayed light or heavy.

Thin Film Coatings are generally spayed at the sheen you want as an end result. When spraying, it should take about 3-4 passes with your spray gun to get to full color. Check your material flow to be sure you’re not spraying too heavy.

Why Can’t I just use old towels or newspaper instead of this mat?2018-08-26T15:04:52-05:00

Old towels and newspaper can make a good mat to clean your gun on, however, they don’t absorb fluids like polypropylene-based materials do. Those fluids can end up staining your floor or your table and sticking back to your gun as a result. Our engineers designed the KG Gun Cleaning Mat to absorb as much gun cleaning agents as possible. It also has a flat, plain surface that makes cleaning more convenient, as opposed to fabric and paper that can get wrinkled while in use.

Why did the finish come out rough?2020-01-14T22:11:42-06:00

All of the coatings KG produces should come out  smooth. Rough finishes are generally caused by too much air pressure, the substrate being too hot, too little material flow, how far the spray gun is held from the substrate or a combination of these. Adjusting the air pressure, material flow, preheating and holding the spray gun the same distance from the substrate is critical and when accomplished will yield a smooth finish.

Of all the reasons mentioned above the most common is too much air pressure with the substrate being too hot. This will cause the coating to dry before it hits the part, creating an almost grit like texture.
