POR-15 49229 Cycle Tank Repair Kit

Have used this product on several tanks. does a great job if you follow instructions!

J'ai utiliser dans le joint du reservoir d'une voiture. Pas suffisant pour le reservoir complet mais parfait pour rendre étanche le joint.

This product worked well for a moderately corroded gas tank from a Honda CB450. Mainly low areas of tank were affected by rust where the condensate water tends to collect over time.Recommend for any degree of scale present on inside of tank to use chain and or washers combined with at least half an hour of vigoourous shaking to properly prepare surface.Product will fail if loose rust/ scale is not knocked off prior to application.

I have a 1979 Yamaha XS750F that has been sitting in my garage for the better part of 30 years (though I did clean the carbs and ride it a bit in 2004). The gas tank had about a gallon of old gas in it (more like turpentine) and was caked with a hard layer of crude. After removing the crude and using the POR-15 treatment regime the inside of the tank now looks great.Some responders have stated that this product didn't work and that they followed the instructions in detail. However what they probably failed to do was get rid of that layer of of hard crude stuck to the inside of the tank first. You must remove this hard layer of crude first - and it is not an easy thing to do. First I power washed the inside of the tank. Then I added about a gallon of hot water and added a large cup full of nuts and washers and repeatedly shook and rolled the this mixture around the tank to break up the crude. I repeated this step over and over about 20+ times. I also used a wooden dowel to reach into the tank to break loose some of the crude. After this I filled the tank with 4.5 gallons of Metal Rescue and let it sit for over a week (this stuff also works great).Once I had the hard scaled crude removed from the tank I used the POR-15 treatment regime. I probably didn't need to do the degreaser/cleaner since I had just done the Metal Rescue soak but I did it anyway. The metal prep and final seal coat worked great. I have a tank that is like new again.PS: The dual vacuum petcocks on the tank were removed for this treatment and were replaced with a small steel plate and gasket. The petcocks were also caked with crude and required teardown and extensive cleaning (as did the carbs) - so if you don't have an ultrasonic cleaner I would add that to your shopping list as well.

Works great made old rusted 1973 tank look like new again time consuming process but follow instructions will give you amazing results highly recommend great shipping and service
