I took your advise about not coating my tanks last year. Unfortunately it was bad advise in my personal case. Spent hours upon hours prepping, painting, wet sanding and buffing out my tanks. Plus pressure tested them. Came out beautiful. I was very proud. Six months later I came out in the morning and found my paint bubbling off one of the tanks. I thought I screwed up the prep part. Turns out there was an itsy bitsy teentsy weentsy pin hole in a weld that developed And DESTROYED all my work.

IF ONLY I HAD USED THE KREEM THAT I HAD BOUGHT AND LEFT SITTING ON THE SHELF.

Never again. It is in there now. Just like it was in my old tanks.

Dear Lockdoc,

Are you blaming the welding or no band-aid?

With all respect,

If ya think prepping, painting, wet sanding, and buffing the outside of a set of tanks and havin em leak is enough to push ya over the edge, try removin that sealer stuff from the inside of those tanks!....bosheff

If you think I'm was being nasty or something, fine. Just a touchy subject for me. It was a lot of work. Of course it was a bad weld. Or maybe I sanded a weld when I shouldn't have. Who knows? Welcome to the real world. No one needs any snide comments. I just know if I had used it my bike would have been fine. I have used it before with no problems. Nor have any of my local friends. I decided too not use due to posts here. It was said it peels and can clog stuff. I usually get sound advise here so I didn't. So I'm giving my advise. Use it. I'm the other side of the coin. If your tank is prepped well it should work just fine. My old tanks had a lot of rust inside. Cleaned it as well as I could but it still had rust. The Kreem has yet to peel or chip as I still have them. Just my experience. And look, I wrote more than one sentence so as to try and explain myself. Some others should try it.

With respect, Bill

Just a note. I have to go to court tomorrow for BS so I'm pretty edgy. I might look at this later differently. But I still say use it.

Last fall I coated my new set of repro J model tanks with Kreem, 2 coats. I haven't painted them yet. If I fill them with MEK, any idea how long it would take to strip? Does the MEK disolve the Kreem or does it just come out in clumps, ect......help..Rod

I have to agree with nightshift.......this action is a band-aid at best......sure it might last a few days or a few years and make you happy you did it........but the bottom line is........it "WILL" eventually fail and when that day comes.....I don't want to be there.

Every tank I paint, I always pressure test it for leaks submerged in water.....it's SOP as far as any restoration goes. That goes for new reproduction tanks as well.

Kreem ...
there are better sealers....
redkote is one and por15 the other, I had bad luck with kreem.
it finally let loose, what a pain to get out.

as the gas composition changes, the redkote that is in the tanks may fail but hopefully not for a while.....

I just used the Red-kote product on my '61 tanks. I researched this subject a while and not just on this forum and felt it was worth giving it a try. Only time will tell.

I'm not sure why you would use a coating on an alum. tank ,they don't rust & are a lot easier to weld /repair . I have had no problems using the Kreem product & I personally know tanks that have had them in them for twenty years . My one Pan is going on seven and I know its still good because I just emptied the old gas out last week & the Kreem looks like the day I put it in. Some like it & some don't.

It depends on the resin used in Kreem. MEK might be strong enough. Toluene might be strong enough. But if neither do the job or don't do it adequately try to find a methylene chloride based stripper. That's what our plant (paint mfg) used for decades. Lately they are using methyl pyrrolidone and peroxide based strippers but aren't having the same efficiency by a long shot.

Talk about a head scratcher. How can some guys be using it for decades with out any problems and others have trouble with it almost instantly? Can there be that big of a difference in the fuel mixtures from area to area? Are some guys just applying the coating wrong?

I’ve tried sealers twice on pin hole leaks and followed the directions to the letter. Both times the sealer has failed with in a single season. No more tries for me. Now I just keep the tanks full to keep them from rusting.
