Stefan Posted October 8 Report Share Posted October 8 I have a fuel tank from a 1973 Honda motorcycle which has quite a bit of rust. I treated it with paint stripper to get remnants of old tank liner out, then rinsed with paint stripper wash. Then I applied Step 1, then rinsed with water and let dry. Then I applied RustBlast, moving it around the tank for a full 3 hours. It seems to have had no effect (see attached photos of the tank after treatment). What am I doing wrong? Or, is that tank liner I'm looking at and not rust? (It's my first time doing this) Thanks in advance for any clues!

KBS Coatings Posted October 8 Report Share Posted October 8 During the KBS Klean step, did you use a chain in the tank and aggressively shake the tank to remove all loose, flaky rust? Of Note: RustBlast is designed to etch the rust that is in the tank. This is needed for incredible and long-lasting Tank Sealer adhesion. This is shared to help clear up confusion on the role or RustBlast during the Tank Sealer prep process.

Stefan Posted October 8 Author Report Share Posted October 8 I used a large collection of small and large bolts/screws and shook them around quite a lot. Nothing seems to be flaky or loose. You wrote "etch the rust" -- does that mean I can apply tank sealer over what's in there now and it'll bond to the rust that's left there?

KBS Coatings Posted October 8 Report Share Posted October 8 Just now, Stefan said: You wrote "etch the rust" -- does that mean I can apply tank sealer over what's in there now and it'll bond to the rust that's left there? Absolutely. RustBlast chemically etches the rust and leaves a dusting of zinc phosphate which enhances the Tank Sealer adhesion and the Tank Sealer seals up that rusty surface. What other questions might you have?
