Since I had such a great experience with the Kreem tank liner kit I will try another product.
That tank is out for a new paint job, ( paint bubbles appeared during the etching process).
Seems this product will seal over light rust & stop it. I have doubts about that claim, so I have done the metal rescue bath & will proceed as instructed on the can for application to this tank.

BTW, the rust bath product is a bit darker after this use, as expected...2nd tank

I dont use kreem. Read to many articles about it cracking and breaking away plugging carbs. Red Kote wont do that. Its Good for ten years plus and you can strip it with acetone and recoat it. Ethenol in gas will leach the red color out of it for a while but wont harm it. The new formula wont leach the dye out of it. Guess they had complaints on the leaching of the dye. I do all my tanks with redcoat but strip them clean before applying with phosphoric acid.

Thanks for the info teamster6.
To late for the tank I used Kreem in, it's out for paint, so I will monitor closely for the issue you speak of. I coated that tank twice. That liner is also dissolvable with acetone, so it can be redone if necessary.
Good info on the Redcoat. It was highly recommended by the bike shop I visit for oil & such.

Nothing will remove rust on a tank faster than muratic acid. Problem is it will flash rust extremely fast. To stop this I clean with muratic. Flush with clear water and baking soda. Then immediately hit it with phosphoric acid. The phos acid leaves a zinc coating in the tank and it will not flash rust. Sparkling clean. Then coat the tank with red kote and never any rust again.

I just want to thank you all for your reviews/reports on the various coating products!

I've been lucky with most of my tanks only needing rust removal... with the exception of my 1965 MG1T. ( I used POR15 on it and it's held up great!)

I've recently been working on an Allstate bike from the 1960's that I hope to turn into a "scrambler" and the tanks I've found from the 50's and 60's are pretty bad and need to be sealed.

So I really appreciate the info you're all posting!

Silver Tank #1, 1st one I lined, Kreem
White Tank #2, 2nd tank lined, Red Coat
Virgina Gold Tank #3, was lined last, Red Coat
Aug 2016 I installed Red Coat tank liner into 2 of my 3 fuel tanks. The white, #2, tank in use is holding up well.
Tank #3, Virgina Gold, was coated for storage but used while silver tank #1 was out for re-paint. It is holding well after
being put back into storage. fuel removed of course.


Silver Tank #1 was coated with Kreem tank liner and it has failed to hold. So I will most likely desolve the liner with acetone
and recoat with Red Coat.
I cannot recommend Kreem as a liner, It will not tolerate REC89 fuel. It has split/cracked and started to delaminate from the tank
Will be putting Tank #3 back on while I sort this out at a later date.

+1 on Redcoat. Works over heavy rust in a pinch.
