Fuel tank sealer

[woodypup59]

Has anyone used a tank sealer to repair an old fuel tank ?

Are of these products suitable for high ethanol petrol blends ie 15%.

Slosh seal says it's been tested with dilutions of up to 85% corn ethanol .

I have used a 3M product called slosh tank sealer.
I got the last lot from Frosts with an etch fluid to clean the inside before addiing the sealer.

Its still going strong after 8 yrs !
