ZINC PHOSPHATE PARKERIZING Reviews & Ratings

A very user-friendly process that produces a non-metallic zinc phosphate coating on iron and steel that is highly resistant to corrosion, very durable and long wearing. The traditional, charcoal-gray color is ideal for non-glare finishes on tactical and hunting guns, or restoring older military guns. The large, uniform grain structure and even thickness coating gives excellent retention for lubricants and rust preventives. Also provides an ideal base for spray-on/bake on finishes such as Brownells Baking Lacquer, Aluma-Hyde II and Teflon Moly Gun Finish. The porous surface produced by Zinc Phosphate Parkerizing actually bonds the final finish to the gun for a durable, long wearing coating. A very clean process, Zinc Phosphate leaves almost no sludge buildup around the heating coils in your tank. If you are already setup for parkerizing, switching to Zinc Phosphate is a simple matter of changing chemicals in your tank. SPECS: Net Contents: 1 gallon (3.8L), 1 pint (473ml). In plastic
container. Full instructions.

Zinc Park Solution

Understand the process and the key parts of the instructions - for what you are doing, and it's simple. Results will vary depending on steel properties. Mho on musts: Blast w/ aluminum oxide #100 Degrease thoroughly before & after blasting - I used acetone. Age the solution properly - Iron filings - like 12 bucks delivered from the big A. Distilled water for pre-dip and solution dip. Watch the process & temps carefully - this solution doesn't take long. Pics can be deceiving - I got a beautiful, dark grey with a slight greenish hue, with the frame slightly darker than the slide. There WILL be variations in the color of components. Again, it's the steel. You won't know final colors until it's aged some with your choice of post park oil soak. Tisas 1911 a1 frame, slide & msh. (This frame & slide are some of the toughest steel I've worked with) Everything else EGW, Harrison, Kart.

Fantastic results on the cheap.

I've piled up a few project guns over the past few years that I wanted to parkerize, and I finally decided to get around to it, and I'm super happy that I did! The included instructions are easy to follow, but detailed enough to make sure you have the necessary information, and following those directions I was able to use a soup pan and a hot plate to create a finish that is indistinguishable from factory parts! I'm EXTREMELY happy with my purchase, I would HIGHLY recommend this for anyone looking to get into parkerizing (especially considering the cost), and I will definitely get more in the future when mine runs out.

worked great

I was hesitant to use a product for the first time on a firearm I spent so much time building but the results came out great. I started with a sample piece And did everything contrary to instruction just to see how much lee way there was. To my surprise the piece came out perfect. For the actual gun a paid a lot more attention to the instruction which were very detailed. The video was also very helpful. The end results was was a very even color. On the small test piece I had done I tried maring the surface and it took a pretty good effert to put a scrach in it.
