KBS Coatings 52000 Cycle Tank Sealer Kit, Complete Kit - Seals Up To 5 Gallon Tank, Lightly Pigmented Silver

I watched alot of videos on using some kind of sealer for an internally rusted up motorcycle gas tank. I settled on KBS because it was easy to use, and results were great. After using this product and following the instructions i now have a rust free, sealed tank that will never rust again. This stuff is unbelievably hard. The only suggestion is if you have a nicely painted tank, wipe it clean after each each application. Use wd40, or any penetrating oil on the outside of the tank to protect the paint. i didnt do that and i thought i'd just wipe off the redidue and be good...i now have small streak marks from the etching solution. my fault. but the final sealer results are better than expected. this stuff is super great! i now have a new nitch and service to provide because where i live , nobody offeres this. Probably cuz its teadiuse and takes a good week to get the best results. but worth it.

This stuff worked exactly as advertised. I did the gas tank on my 1986 Honda Shadow that the previous owner had let the gas dry out in the tank so it had a lot of rust and dried varnish. I watched a few videos before even ordering the kit and felt like I had a pretty good grasp of what I needed to do for this to be successful. My favorite YT video was Cory on MotorcycleMD, who runs you through EVERY step of the way.The biggest concern I had was that my tank still smelled like gasoline after using the cleaner, so I cleaned it twice more with 5 parts hot water:1 part Simple green, dryed it out, then rinsed with 1 cup of Acetone before moving on to the etching Blast. I also had 1 pound of 1-1/4" wood screws inside the tank the whole time of cleaning and etching. Don't stir the paint for more than 5 minutes before dumping into the tank because it starts to thicken pretty quickly.The 3 days of drying didn't present a problem for me. If you are doing your tank, you should be doing your carbs too. I did my tank first, then the carbs while the tank was off the bike and curing. You can put your bike back together during those 3 days, you just can't put gas in the tank. I've got about 500 miles on the newly lined tank now and everything still looks perfect inside the tank and the bike runs like a top.I'm going to do my 92 Yamaha VMax next and the only thing I'm going do differently is to pre-clean the tank better before starting with the KBS cleaner.

Works excellent for sealing JustRite five gallon gas cans.

Pretty easy to use, it took me a week from start to finish but i wanted to be through. This kit is designed for tank size 5 gallon. If you have a smaller tank like me I suggest reducing how much coating (final step) you use. My tank 3.9 gal/ 5 gal = .76. Do .76 x 8 ounce of tank sealer = 6.8 oz of sealer. I used the whole can an could not get the acess out. That caused clumps in the seal

This stuff worked amazing for me. I can’t say how the sealer works because I chose not to seal my motorcycle tank. I used the degreaser and the acid etch. The acid etch solution totally cleaned any rust that was in the tank. I used sheet metal screws with the acid etch solution and was AMAZED at the outcome.

Good product, saved an old gas tank, has held all winter..... so far.

This stuff is great. I used it on a '75 Honda XR75 tank that was quite rusty inside. To the point of rust flakes coming loose and clogging the petcock, fuel lines and carburetor. Before this, I tried many different cleaning techniques to get rid of the rust, but to no avail... no matter how much I got out eventually rust would redevelop and clog the system. The key with this (that's not really clear in the instructions) is to use the cleaner several times, filtering it and re-administering it into the tank. I'd pour in the cleaning solution, add about 100 1/4" self-drilling screws, shake the tank back and forth for 10-15 minutes. Then drain, rinse, and inspect the interior with a fiber optic camera. I probably repeated this step 15 times before I could see all the (loose) surface rust was removed from the tank walls. When I was done there was still a fair amount of surface rust, but nothing that was in jeopardy of breaking loose. After that the rest was easy. I will say that I let the "rust blaster" etch the tank for about 2 hours with rotations every 5-10 minutes. I used duct tape over the petcock and gas cap orifices, which worked, but I had to make sure I didn't let either the Cleaning or the Blaster solution sit too long on the duct tape covers or they'd start to leak. I also waxed the painted surfaces of the tank, because I didn't want any of these solutions to damage the paint... I'm not sure that was necessary, but it didn't say anything about that in the instructions and this tank has "cherry" paint. I put a little grease on a petcock bolt and threaded it into the tank hole to prevent this sealer from clogging the threads. It took 2 days to clean, prep, and coat the tank and another 4 days for it to dry. I didn't have any pin holes before or after the cleaning/etching, so I can't comment on how well it would seal those. Now with this epoxy coated interior, I have no fear of future rust issues.

Easy to use
