Gun-Kote
If I use this finish on a knife, say 1095 or 0-1, how can I expect the pre-heat to 125*F and the bake time of 325*F for one hour to effect my temper?
My guess is that it will do nothing to the temper at less than 400*F or so, but I hate guessing with such things.

I've used Gun-Kote extensivley for the last several years. As long as you don't exceed the tempering temp you won't harm anything. One note...if your going to use it on a straight steel blade, it will hold best with a bead/sand blasted finish that is CLEANED well prior to applying the gun-kote. The coating is very thin, and any scratches or marks left in the blade will show in the coating.

Thanks Ed. I'm headed to HF for an economy blasting cabinet next week. I've heard great things about this coating. I hope it works on projects.

If everything is done right, the only way to get it off after baking is to sand it off. When I first got it I thought it would be a time saver on the military style blades....thought it might make it so I didn't have to finish too far. Man was I wrong! I did a scothbrite belt finish on a Utility/fighter blade and then Gun-Koted it. The scotchbrite marks GLARED through. OOPS!
I refinished that blade down to 600 grit by hand and then blasted/coated it. Worked great. __________________ WWW.CAFFREYKNIVES.NET Caffreyknives@gmail.com "Every CHOICE has a CONSEQUENCE, and all your CONSEQUENCES are a result of your CHOICES."

Guncoat with Chemfos and or Molyresin?
Chemfos (zink phosphate) applied before Guncoat will provide a massivly stronger and more even / thicker finish. I work with e-coat all day long and nothing works w/o the phosphate crystal morphology and coating weight there for the paint to latch on.
Now, there is something out there called Molyresin. http://www.molyresin.com/ Its a non paint mega tough super duper thing.. i'm going to try it out. Good luck to you. Many gun freaks have reported great success.
