Hi Colin

Zinc Phosphate I take it you are using the industrial coating type that is applied hot or hot dipped? Not the automotive metal prep.

Reason I'm asking that since basically all use gasoline has 10-15% ethanol it is playing havoc with many of the traditional gas tank coatings. It also tends to make tanks that have never rusted before rust.

So I'm trying to figure out how to make new tanks for the CMP last. Interestingly the tanks on the C60L Pat 12 built in 1941 is just mild steel, as is the C60S Pat 13 built in 1942. But my HUP tanks appear to be lead coated both inside and out.

Thanks for permission to use the photos.
