Parkerizing Solution

[LeeEnfieldNo.4_mk1]

OK, so after some research I discovered a reasonable home parkerizing solution that is apperently very effective. This solution is:
1 Gallon of distilled water
1 shot (approx 1.5 fluid ounce) of Phosphoric Acid
1 shot (approx 1.5 fluid ounce) of manganese dioxide

I have located some phosphoric acid at a local garden center, the problem is that it is two parts water, and only one part Acid (about 33% acid). Is this still usable? Do I just add say, three shots instead of one?

I am still looking for some Manganese dioxide, I may have to order it in from a pottery supply store another CGN'er told me about.

Thanks.

Manganese dioxide is available from the Pottery Supply House in Oakville ON. $7 for a 1 kg bag. They do mail order.

I have used this basic recipe to park two Lee Enfields and a Shillen target barrel. I subsequently Guncoated then allo not sure how well it works on its own. Seems to make a great Guncoat base. You can probably find the detailed recipe on the internet by Goggling "Parkerizing Gun Finish by G.A. Boss". If not, PM me your email address and I will send you a copy.

Cheers

The recipe I have uses 3 oz's ea. of acid and Manganese. Same for zinc 3 oz.
I've never had a problem. Add a bisquit of steel wool. Just make sure you let it cook for 10-15 minutes to dissolve the manganese before you add the parts.

OK sweet, I will go get the acid tommorow. I got a 12 quart stainless steel pot from Canadian tire for $15 that is high enough to keep splatter in the pot, and large enough to do a pistol. Now I guess I need to order the manganese dioxide and pick up some emery cloth and glass beads to prep the metal. Thanks.

if you live in the lower mainland you can get the maganese dioxide from Green Barn potter supply in Surrey. they sell it for $4.00/lb.

Is the fact that the acid is only 33% a problem?

Since your original recipe calls for 1 shot acid to 1 gallon of water, and the acid you have available is at 33% strength, I'd try using 3 shots and do a test piece on some scrap steel.
