William Barnes Posted July 19, 2022 Report Share Posted July 19, 2022 When treating a large steel diesel tank, such as in a boat, all the rust is at the bottom when water will lie. It is impossible to treat the interior of such a tank with 100% confidence of no gaps, when working through an access hole. What surface preparation will maximise adhesion between a partial coat of tank-sealer and diesel? Will sand-blasting, and/or using salt-water (to create a fine layer of fresh rust for good grip) help? Quote Link to comment Share on other sites More sharing options...
