Here is a heads up for those of you who buy Park Kits to do their guns.  I ordered a Large Black Manganese kit from Calvan.Com back on March2nd and still have not received it yet.  Emails go unanswered.  I called them and talked to some A$$hole who was about as rude as they come.  Told me the kit was shipped on March 9th.  WOW it took 7 days to ship the kit.  Now it is the 17th and no product.  Complaining aside DO NOT order from these idiots.  Looks like I have to make up my own park kit.  Should have done from the start.  

Quoted: bummer The long tanks are the hard part to get best deals on, and welding stainless is not a job for rookies with this material.

I have the tanks, just need the stuff.  I have been reading about the park process.  A chemist I am not.  Trial and error is the way to go.

Yeah I got the hint before ordering. They do not answer any emails with tech questions etc. Where to go next for reputable supplier of chems? Here is a website for you:http://www.parkerizingtanks.com/

Still checking them out........................ good info.

Best guess is to go with the established companies like Brownells:http://www.brownells.com/aspx/ns/store/ProductDetail.aspx?p=1110&title=MANGANESE+PARKERIZING+SOLUTION+%26+KIT

I finally got the kit,  only took 22 days.  I would say STEAR CLEAR OF THESE ASSHOLES.  Customer service is non existant.  I had to file a complaint with my CC company to get them off of their asses.  I am afraid to used the product.  If it is as good as their customer service it will ruin my gun.
