[ARCHIVED THREAD] - Gun kote won't stick-what happened?

Posted: 2/17/2006 10:22:10 PM EDT

Ok I've been painting my ARs/parts with this stuff for a couple of weeks. First few sets of lowers came out great. Stuff wont come off. This week I painted a M1A SAGE stock with the same stuff / procedures and the GK just flakes off. I had a couple of other pieces I did at the same time but in a different color and that stuff, baked in the same over, is hard as a coffin nail. Any ideas on why it works one time and not another?

Open for suggestions

Usually the problem is in the prep. The surface should be sand blasted with Aluminum Oxide sand blast media and not any media with Silica in it. Gun Kote also sells an etching type stuff you spray on before applying the GunKote that makes it stick better. Also watch the temp. and humidity when you apply the GunKote. Cold temps aren't good and high humidity can also be bad.

If you paint a slick surface without prep, the GK will just peel off. The AR stuff may have been rough already or etched from the factory so the GK stuck well.

First, you have to degrease.

When you are done with that.................degrease.

When you finish that....................degrease.

Use gloves when handling degreased parts.

Preheat the parts.

Spray GK with an air brush.

Bake.

Did I mention degrease upfront?

Thanks for the words

I think the problem was the sage stock. It was anodized but it was still a little slick. I sand blasted it today and will give it another shot.

I wonder if I should degrease it or not

It may have been Teflon coated also

That, sir, is a fact, especially with Norrell's tan.

I'm not a fan of Norells TAN.

What's wrong with Norrell's tan?

I sand blasted it and gave it another shot with the KG tan. It's not coming off now-stuck very well. I just bought a blasting cabinet so I could do some more parts. Not going to have very many all black rifles in a few weeks.

In response to Teknic's comment, does anyone know if one color will stick better than another?

It doesn't adhere well to teflon surfaces like the Mega receivers. In general, the pigment used is heat sensitive, and affects the overall durability. It seems fine on most surfaces, but it was a large disappointment for a few of us on the Megas.....

I used the Norrell's tan on a stripped lower and am planning to use it on more parts when I get them. My oven doesn't hold temps very well, should I expect variations in the color?
