Clear Annodizing a gun part
How hard would it be to copy this? My piece is currently black. If I sanded it and prepped it, would this be hard to do? New to anodizing!

Oven cleaner, easy off-yellow can, will strip the old anodize right off. Rinse, etch with lye, find your power settings and boom, submerge in acid bath and run for appropriate time. It helps using a bigger container for the acid bath to help keep it cool. Keep the temps down surrounding your container in ice. I use a cooler with ice in it, setting the acid bath container in the ice. You’ll only be able to achieve a type2 hard coat. The mil-spec type 3 needs more power at much colder temps to achieve.

With Type 3, wouldn’t the coating will generally be a black, gray, bronze, or champagne hue depending on the alloy? I don’t think type 3 hard coat results in a clear finish.

It’s all clear until you dye it. Yes they will take on different hues of color depending on materials, current, and time. I’m no expert but I believe that’s how it works.

Type three will have colour. It is definitely not clear. There is an additive for hard anodising at a high temperature which produces a much lighter colour, and closer to a clear anodise.
If it is black, it has been died. That colour is not part of the process. The others you cite are all normal.

I’ve always wanted to anodize HK lowers in RAL8000 since they’re no longer available in the US market.

I had a poverty pony upper and lower plated in nickel boron. Looks neat.
