Flamemaster is the brand that Van's A/C is supplying now; I bought some pourable stuff from them a few years ago. Caution: if you didn't thoroughly clean the entire inner surface to prep for the 'slosh', it will likely peel off in sheets at some future date. Many RV'ers have had to cut open their tanks to remove peeling sealant. If it's a welded tank, have you thought about trying something like 'Alumiweld'? http://www.alumiweld.com/h2uaw.html It's actually a type of brazing or soldering for aluminum, since you don't melt the underlying structure.
