I've never used that one but I have used two others (happens when you buy a lot of old POS's!)
Kreem used on an old /5 Beemer tank. End result was OK but it was a pain to work with and I am not sure it got all the old junk out well. IIRC the instructions were to add rocks or old bolts etc... into the tank with the mixture and shake vigourously!
POR 15 on the other hand used a chemical reaction to etch the inside of a Yamaha XS850 tank and then the coating bonds with that sort of. Better product IMO.
