I bought a engine kit for a motorbike and the instructions recommend sealing the fuel tank with a sealant. Because this is a new tank is it necessary to go thru all the cleaning, etching and then sealing, or can I go straight to sealing the tank?

Yes. It would be best to seal the tank with the entire 3 Step System. A new tank is extremely slick and usually has a protective film on it. You will want to use the AquaKlean (http://www.kbs-coatings.com/aquaklean.html) to clean the protective film off of the inside of the tank. And you will want to use the RustBlast (http://www.kbs-coatings.com/rustblast.html) to etch the slick surface of your new tank so you get a good surface profile to which the Gold Standard Tank Sealer (http://www.kbs-coatings.com/tank-sealer.html) can adhere.
