gas tank pin holes

did not use the kreem

decided after research on here not to use the kreem, also because while trying to clean out the tank I couldn't for the life of me get all the rust out. I coulnt see any rust but when I shook it I sure could hear it rattling around. SO... I took it a local well known radiator repair place and let them deal with it. They cleaned it out good and used the red kote stuff. Only complaint I have is they did not let the excess drain out so it wouldn't dry. When I picked it up they said it was done so I stuck it on the bike just so it would be out of the way until I paint it and it leaked out all the excess (about 4 ounces!!) onto my bike and newly rebuilt carbs!! Luckily it cleaned up with some acetone and I started turning the tank to spread whatever was left. Shoulda did it myself, thats what I get for being lazy and letting someone else do something I could have done a better job if I did it myself. Another lesson learned. Man there are some crappy shops around here, no wonder no one trusts mechanics in chicago.

devcon

i've been riding with the devcon repaired gas tank for a couple weeks now and it's working fine. there were a bunch of holes measuring from 1/16" to 1/4" along the seam. devcon dries almost clear, barely noticeable.

I've used the POR-15 motorcycle tank repair kit with great success as have some others here. The kit comes with everything you need including patch material for the larger holes. If you don't get the rust problem totally uinder control by sealing the whole inside of the tank more pinholes will appear in the near future , especially along the bottom. If you're painting the outside of the tank these pinholes will ruin all your hard work. Do a forum search on POR-15 for lots of info. Just make sure you leave lots of time between each procedure.

A while back guys were recommending taking your tank to a radiator shop and for $35 or so the shop would seal it up completely.

It's called Hot Tanking

Did it!! They even fixed the hole for that price!!

Sorry for bumping this old thread but I wanted to ask you guys who did the hottanking.... buttonhook and rusty boltz.... How the radiator shop did with the tank. IE) If I have a nice paint job on the outside, no leaks, but a ton of rust, would they be able to clean and seal the tank without damaging my paint? Any advice welcome

Its been about a month since painting and is holding up well with a full tank most of the time, time will tell I guess.The hot tanking was done by a place in Chicago called Cool-Heat. They did a great job cleaning it and after I JB welded the very small hole they pressure checked it at something like 50psi and it did not leak. My complaints are they took a week to do it after they told me 2 days and they didn't let the excess sealer out which ended up on my bike and garage floor. I paid 60 bucks but do not recommend them as they were not very professional at all and did not finish the job. I think your probably going to have to repaint the tank if your going to take care of the rust properly. If its heavily rusted inside its likely that some of it is working through the tank. If you don't the rust will eventually take care of your paint and your tank. I got lazy with mine and let someone else do it and regret it, I could and would have done a better job myself. I should have only let them clean it and took care of the sealing myself as no one will take more care of your stuff than you. Besides what bike doesnt look great with new paint!

Thanks for the response. I've already got new paint, so I'm going to strip and coat it myself, based on what you said and some of the radiator shops I called. Thanks again!
