Title: Kreem gas tank liner
Post by: fjman on May 07, 2014, 10:56:16 AM
After buying a new set of tires for the fj. I came up with the idea that I  might as well coat the tank for preventive maintenance in the long run. Has anybody here tried using this on the tank?

If it ain't broke, don't fix it.    :nea:

Many horror stories associated with that stuff.

Admittedly, a lot of those were due to poor surface prep, but why mess with it if you don't have a problem?
IMO, If you're just looking for a worthwhile PM project, try servicing your shock linkage and swingarm.    :pardon:

Ask Marsh how well that works.

Don't do Kreem, I've heard baaad stories about it failing due to poor prep and ethanol.  :bomb:
You shouldn't need to line the tank unless it's damaged. Rusty? Try Evapo-rust or electrolysis if your filter is clogging. If you need to line it, Carswell coatings has stuff with a good reputation. (There was a lot of talk about this on the KLR650.org website.)
I agree with not-a-lib, don't go there unless you have to. :empathy3:

I used this stuff a few years ago thought I followed directions to a tee. After two years I had some fuel starvation problems and found some 'kreem' pieces floating around and ended up plugging fuel outlet and almost plugged my fuel filter. I believe it is a good product but pre prep and etching to the extreme may be required. I doubt I would use it again... would like to hear if there is a better product someone else here maybe has experience with.

Several local guys in the VinMoto group have reported great results with the Red Kote, but they're most always repainting.

I agree mostly with the above. My old tank was Kreemed by a PO.  After I put a few dents in it I decided to replace it with another tank.  Out of curiosity I did a good inspection and I was expecting the Kreem to crack or fail in the dented areas.  Well everything inside looked great.  I had no problem with the stuff.
In fact later I will repair the dents and put it back on the shelf.

I don't know when or which PO coated the tank, if it was done when new or in very good condition that might have contributed to the success of the coating.  As with any paint product the prep is the key and the FJ tank is not easy to clean or prep.  There are areas in that tank that you can not see or get to so you are depending on the "slosh around"  method and hopeing you got it clean and sealed.

Personally I wouldn't do it on an older FJ tank unless I had no choice.  If you have a gravity feed model of FJ you can't even install a good line filter to assist in keeping the carbs clean if the coating fails.

I vote for leaving your tank alone........

A WCR or so ago Marsh had fuel issues, took his carbs apart at the rally, they were full of his tank liner.... Anyone remember what the brand was?

Going Socratic on us...?  It was Kreem!?!  At least that's how I remember it.

If you've seen epoxied garage floors you may have noticed different quality levels...  some peel, some chip, some scratch, and a few do exactly what they are known for (none of that shit).  The difference is prep and the only guy I know with a great floor (he lurks here and stalks me I think, so he'll read this) was absolutely crazy anal on the prep.  The results are still very nice after years...

I'd ask why?  A little surface rust isn't going to cause an issue and if you keep the tank full while parked at home, that's all you're likely to get.  Just get the tank clean and use it.

IMHO of course.

Huh, a video boreoscope would be damned handy for checking the condition of your tank's guts, from the current state, to the amount of prepwork done, to the condition of the chemical liner.

:lol:

Yeah...I've done 30,000 sq ft epoxy floors in some of the companies I've moved.  It's ALL in the prep!  I could see where someone was getting lazy right by one of the 14 foot roll up doors and sure enough...I had them back two weeks later to grind off, shot-prep, water seal and re-epoxy that exact spot.

As George pointed out, it's not quite as easy to see the prep in the nether regions of the FJ fuel tank!
