I have my reciever all ready to assemble. I have read that the reciever can distort during heat treating. A friend of mine who will be parkerising my parts wants it dissasembled for the parkerising because he said all the acid does not wash out? Should I heat treat, parkerise, then assemble. Or Assemble, Heat treat, then Parkerise? Or should I abandon the parkerising altogether and alumahide?

Thanks

I would heat treat, park, assemble.

I would think that heat treating after might screw up your park job.
Although there is nothing wrong with using Alumahyde, I have done several that way, I wouldn't pass up a free park job.

Is your friend parkerizing or phosphating? The two are really quite different. But both can be neutralized. Your friend should check out what needs to be done to neutralize the metal after the bath. A lot of people say that they are parkerizing but really their phosphating.

I prefer to phosphate, it's easier, and I believe it provides better protection that parkerizing. http://www.parkerizingtanks.com/ has info on their discussion forums, plus other good data. Hope this helps.

The guys pretty knowledgeable so I will say Parkerizing. I will ask him though.
