Evaporust by the barrel?

Anyone purchase a 55 gallon drum of Evaporust. I have three classic Mopars to restore and I am thinking about a "wholesale" purchase of the stuff. The reason being the local Autozone has been the only outlet in this town to sell it and today they started offering the quart size in place of the gallon. No way will that work!

My first contact with a Mexican distributor quoted me $950.00 plus tax which is costlier than offered in the U.S.A. but what is a guy to do?
