Kreem Tank Liner
« on: July 13, 2011, 07:48:49 AM »
My tank liner is peeling and were the tank surface is exposed there is rust. I've had liner in my bowls getting past stone filters, flushed tank and now using paper filters with better results, but rust is colouring fuel and with warnings from supplier of flow restriction.

I get the impression from the "kreem" instructions that i need to strip the old liner as its peeling so as to be able to etch the metal for good adhesion.

Q 1 - Has anyone used this product?

Q 2 - Has anyone used this product over the original peeling liner with success?

Q 3 - Acetone,methyl ethyl ketone are suggested as removers of old "Kreem" but what do i use to remove old liner? Same ?

Q 4 - What has anyone used to seal openings in tank for various stages esp. stripping and re-linning .

I think it was the 'Tank Kreem' product that I originally did my tank with decades ago.
During a long period of storage it flaked off and it took a lot of work to get it all out ready for a new tank liner.
I washed the old liner out with thinners (and plasterboard screws). Paint stripper probably would be more effective and is recommended by the POR people.
I used the POR-15 tank liner kit with good results.

I've got an '84 LS that had a rusted tank and missing liner .

If you've ever heard about using molasses and water to remove rust, I tried it and it does work, but it takes a few weeks .

The by-product of molasses and water after a 'fermentation' is acetic acid, the acid in vinegar .

You can use vinegar and it will remove the rust and old liner .

One of our members here, Crossrodes did this last winter, you may want to send him an email, as he doesn't log on here to frequently now and ask him about what he did .

Another method of removing rust, but not so sure if the liner would come off, is electrolysis .

After you get the rust and liner out, put phosphoric acid in the tank and swirl it around to treat the bare metal .

I used the POR-15 kit .

Doing it again, I would just get the sealant and not the kit, for a really rusted tank, the two bottles that are in the kit just won't get the job done .

I coated my /6 tank with Kreem in 1988.  I used all the stuff in the kit and shook it for an hour or so with nuts, bold, small gravel and sand inside to get out all of the original liner and rust (stored with gas in it for three years - yuck!!!).  It is still fairly clean inside today.

On other tanks I have used the POR 15 tank sealer.  I think it is a better product.  It seems to be thicker and harder that the Kreem.

Be sure to follow the instructions to the hilt on either of them and be sure, be sure, be sure to dry the inside of the tank before you apply the sealer.  Did I mention to ensure the inside is bone dry?

Suerte,
Teo

Cleaned rust out of a Tank w/CLR, worked good, use paper filters.  Read you can use Muriac Acid for Swimming pools to clean out tank liner.  I think I will use that on another tank I have to do, then do the POR 15 treatment to finish clean/prep and then line.

For the most part the Kreem liner is not that good.  The products from POR15 and Caswell Plating are much better.  I've had excellent results with POR15...

The guys from the BMW MOA forum suggested POR tank cleaner -  I used it and it's way better than Kreem (I've used that too).  POR is the way to go - inside of my R65LS tank is like new.

+1 on POR. Have used it on several of my bikes. Just make sure to follow instructions to the letter.

The original liner is red - perhaps you thought it was rust? And it comes off in fine particles that can collect in the float bowl - it's not rust but the original liner.

I've heard lots of bad reports on Kreem and wouldn't use it. Go with POR 15 or one of the others. I've heard there's a good one that's even red like the original.

I've seen several Kreem jobs fail.  I like POR-15.  They make a "Heavy Duty" motorcycle kit that includes a bottle of stuff that will dissolve the old Kreem.  So you get Marine Clean, that eats varnish and gum, the stuff that dissolves Kreem, Metal Ready which removes rust and etches the metal, then a can of hte POR-15 which leaves what looks like a thin coating of silver paint inside your tank.
MEK will dissolve a bad Kreem job, but you have to be very careful to keep it off yourself and any painted surface.  It dissolves everything.
Good Luck!

Kreem is very thick, POR-15 much thinner.  I prefer POR-15 too, but have used Kreem successfully.
