I know that FGCI has it. The only problem is they only sell it in 5gal quanity. Ringleader bought it and is deviding it up in small quanities over on ClassicMako.com
Now I have heard that Shrwin Williams pant company has it. I haven't checked. Check you local yellow pages for SW dealer.

SW does carry it.... but still in a 5 gallon kit. My 29 year old un-coated aluminum gas tank was in good shape except on the bottom were someone had placed 5 rubber adhesive strip's. When I inspected the tank I peeled off the rubber strip's and there was severe pitting under them. Thats the only place there was pitting on the whole tank. Pascoe on his web site says that rubber has carbon in it which will react with the aluminum....He is right!
I'm not sure if it's really necessary to coat an aluminum tank with anything. As long as your tank is made of high quality materials by someone certified to do so and you install it in a way that it is not in constant contact with water and gets good ventilation they will last the life of the boat. That said I went ahead and coated my new tank with coal tar... I figured what the heck it cant hurt to do so. [img]/images/graemlins/grin.gif[/img]

I have fabricated many fuel tanks for myself and others(5052 H32 aluminum- we are fabricators), and have zinc chromated them, properly ventilated, etc..In salt water exposure, they still pit and corrode if salt water is in contact for very long. Last winter I built a new fuel tank for one of my boats (four boat theory) and had the local Line X it dealer coat this tank (used on pickup beds). Cost me $100.00 for a 120 gallon tank. I am very happy with it.

Strick, when S and P Sheetmetal made my tank I had them epoxy coat it, then I put neoprene strips on the bottom with 5200. The neoprene does not come in contact with the aluminum. I'll e-mail you a picture of the tank.-Paul
