Hey fellas......I've been looking around for some blade finishes. I saw the thread where a fella tested some KG Gunkoat and it held up quite nicely to some abuse. Does anyone know of any other products that can outperform KG Gunkoat and give an almost bullet proof finish? Any thoughts and opinions are muchly appreciated. Cheers Art
 
The gunkote DID NOT work for me 100% of the time. I bought some OD color for some daggers I sent to Iraq...all I did was take everthing down to 220 grit, clean with acetone and spray & bake.....so far, so good.

I then bought some black for another knife and bead blasted it, per their instructions, cleaned with acetone, spray & bake....peeled right off! Twice! Went back and scuffed it up with my scotchbrite wheel, etc....peeled right off! I got to thinking this stuff must not be the same from lot to lot or color to color....I don't know. I never figured out the secret to getting the black stuff to stick.

I do know that a recent magazine article regarding a new hunting rifle mentioned during the R&D phase of production of that rifle that they tried Cerracote (spelling?) and another similar product and that they settled on Cerracote, as the other product sucked....their exact words. I am pretty sure from their description that the other brand was gunkote, but obvously can't be 100% sure.
 
Gunkote, duracoat, and powder coating. I have powder coated close to 2hundred knives without much problems. It is user friendly low cost and is very tough.

http://www.eastwoodco.com/

The above company has a forum dedicated to powder coating and sell great products I purchased the textured black and its really good looking and durable.

2 pounds of powder works out to about 100 to 125 knives

I found gunkote and duracoat to be messy and exspensive buts thats due to my lack of knowledge of the product.

You can purchase a gun for about 130 to 200.00 look at ebay, sears and eastwood

Thanks for the replies fellas......Any idea what Busse uses for their blades. I have a couple older models and they have a black crinkle finish, pretty cool stuff. Cheers Art

Its powder coat and the powder is called Krinkle, but unless you use a good gun the powder is very heavy and will not stick to blades ( will not retain a good charge )

Try sand blasting it to 120 grit aluminum oxide, no finer and make sure the media is clean (ie. no oil or grease contaminants).

Wash the blade using dishwashing detergent, wearing latex gloves. Dry thoroughly. Heat up the blade to 80 to 90 degrees fahrenheit.

Shake can (I used the Gunkote spray can that Brownells sells) for 3 minutes. Spray on a thin coat. Wait 30 minutes with a household fan blowing on the blade, make sure the temperature is around 80 degrees. Recoat, wait 30 minutes. Flip over and repeat.

Bake at 300 degrees, do not exceed 325.

*I check all temperatures with a digital thermometer. My household oven goes way over 300, when it's set at this temp. I leave it at 275 and the highest it goes is 315. Also, thin coats! Thick coats chip/ peel off easier.

This is what worked for me. Hope it helps.
 
I usually don't have access to a bead/sand blaster....do you think finishing to 120 or 220 grit would be sufficient? I had to go out of my way to get it blasted last time. Would be a pain in the drain to get em blasted every time if I can just get away with me finishing it to a specific grit.

Thanks,

Hank
