[AT] Phosporic acid - where to find it?

[pga2 at hot1.net]

Most likely what you are looking for is under the brand name "Ospho".
It is made to be painted on, but you could just pour it in, roll the tank 
around to insure complete coverage and drain the excess. It is recommended 
that the excessive, loose rust be removed first, but you've probably already 
done that.

>Hey all - I've got a rusty gas tank I'm cleaning out.  I want to use 
phosphoric acid so I don't have to use a sealer once the tank is cleaned.  
But doggone if I can find anybody that carries this stuff.  I called a couple 
lumber yards, Menards, Fleet Farm, and Sherwin Williams - everybody has 
Muriatic acid, but no phosphoric acid.

I'm told Sherwin Williams carries this product...can anybody give me a brand 
name or some sort of product name to identify the stuff rather than 
just "phosphoric acid?"  I don't think most people I'm talking even knew such 
a thing existed.  I figure a brand name will help out.
