I've used the Eastwood sloshing compound on two occasions to seal up cleaned out gas tanks. It worked very well in both tanks. The coating started disintegrating after about 20-25 years and I replaced both tanks with new reproductions.

What kind of truck are you working on? The AD tanks available today are built in Canada and are very high quality and less expensive than paying to have the tank boiled out and sealed.
