I have used Kreem several times to repair both automobile and cycle fuel tanks that were rusted on the inside. I've also used it after drilling holes in dented cycle fuel tanks to use a dent puller. After filling the holes with JB Weld and finishing the repair with Bondo and other normal body repair products, I applied Kreem to the inside of the tank. I have never experienced a failure. Kreem is good stuff.
I just finished applying KREEM to my wife's 1985 Virago VX 1000. Tank was showing some rust and had tons of gas varnish in it, NOT anymore tank looks better than when new. No more rust problems. No more plugged up carbs and fuel system. This is GREAT stuff folks. Have small leaks ? Not if you use this tank restorer. Gotta get you some.....TODAY !
Fantastic product that works well for old bike restoration. Be sure to follow instructions carefully and I recommend covering outside of tank when using this product as the cleaner can mess up the finish if it gets on it.
This is the second time I have purchased this product from DK and the results are the same, Excellent. The first time was 15 Yr ago in a 71 Honda 750 that had been setting for 8 yrs. When Prep process was complete the tank looked like new inside and as exspected this one turned out the same. Got a rusty tank this is the stuff.
I perches this product because my bike sat unused for four years and the tank needed some TLC. If your tank is used, you will need to spend a fair amount of time cleaning the inside of the tank of rust and sediment. I resorted to a hand full of bolts and screw and a lot of water and shaking of the tank. This isn’t an easy process given you only have a few small openings in the tank. Be prepared to make a few temporary stops for your openings. I used some sheet metal and rubber gasket material with the factory bolts for covering the tank level float whole and shut off valve hole. It’s a lot of work hope fully it will be worth the effort. Good luck!
