I would like to buy Techline ceramic header coating in bulk so I can coat tens of exhaust manifolds. The cans are about 4oz for $25, and I would like to know if I can buy much bigger packaging. I think 12oz cans are available, but I can't find them anywhere. I think a 4oz can would cover a couple sets of manifolds, so I would need 24 to 32oz to cover all the manifolds that I have. I tried contacting Eastwood, but their email form is down, and the phones are closed at this time. Maybe someone here already knows where I can find this?

Did you try the North Americna number at the bottom of this page Techline Coatings, Inc.: Automotive Hi-Performance ™? They list 4oz, 8oz and 12oz packaging.
