My method of choice is electrolysis followed by the Caswell 2-part epoxy tank liner. Works like a charm and the only real cost is the Caswell kit. I've found it's enough for two tanks of this size and vintage. Cheers, N. Once you have the stuff needed for electrolysis Neil, it is an excellent method. And like Evaporust can't it be re-used over and over? Vinegar also works well but is a one time solution. As for just pouring it out, ER is environmentaly safe and you can even put your hands in it with no adverse effects. Just like 2T oil, tires or anything else, lots of ways to skin that old cat right? Everyone has a fave. As for the POR15 it is not the one that had the issues I mis spoke, as Im pretty sure POR works well, but the KREEM is the crap one. For me, 80 bucks has already cleaned 3-4 tanks and over a couple dozen parts have been restored using it too.

You're right Steve, the electrolysis solution can be re-used. It's really just water with Arm & Hammer Washing soda added to create an ionic solution. That, and a dumb battery charger (vs. the newer 'smart' chargers) is all you need.
I tried vinegar on one tank and it flash rusted so fast after I drained it that I ended up redoing the thing with Evaporust.

I did an H1 tank with the 1st gallon I ever bought. It was pretty rusty but turned out very nice. Did a pressure check for leaks and sat it on a shelf in my rust making garage. 3 years later, sold the project and was amazed when I opened the tank to show the buyer. As nice as the day it was done, WOW. They tout that feature in their ads too, no rusting afterwards. I'll keep the vinegar for my cucumber salad thank. No sealers for me either thanks, not yet anyways. I just hope I never have to deal with that bad of a tank. But when its a hard to find scalloped tank or similar, you do what is needed right???

From what I've read, Caswell's phenol novolac epoxy is a safer bet than POR-15 if you really need a sealer. Right on Jim, lots of horror stories about the por15 sealer and ethanol... As for sealing rust under the coating Mitch, sure let it rust out from inside and you will see the holes later. And as for shellac, excellent point. I always fill it with gas and let it sit for a day or so. That loosens anything as a rule. After drying it outside, I then fill the tank with the evaporust. Then let it work for a couple of days. Chrome and stainless stuff with light rust clean up in hours. I used to buy it, a gallon at a time for 28 bucks. Now I can get the 5 gal size for 75 or 80 bucks. You can reuse it many times. Just pour it back through a bit of cheese cloth or a paper towel. If you only get a gallon to try it, you just have to be patient and rotate the tank so it gets everywhere. A few more days are needed that way too. There are a few products claiming to get rid of rust and most work fairly good. This stuff is the best I have used ever. NO, I don't own stock in the co.
Possible Steve I have not used it for this purpose myself yet.. I will try it though as the product has impressed me.. por15 and dom16 cure with moisture so the theory is it's sucks the moisture from the rust and uses it to cure leaving the rust particles dry and incapsolated.. iv used it on my terribly rusty truck frame and rather impressed. The ethanol part may be it's downfall. It claims to be resistant and I have heard good reviews but also some bad ones like you stated.. I also hear some horror stories about women but that doesn't stop us does it lol

Dom16 is a Canadian based version of por15 at 60% the price. One time sealer right over top of said rust. Seals and uses the rust as a bonding agent. I have not used it in a tank yet but know people who have. I have used it for other purposes and love it Mitch - is that the black stuff you were covered with at RB's last year? Man, that bonds like crazy..didn't come off your hide even after sliding along the asphalt track Ian that was a different product lol that's an acid and uv resistant silicone out of Germany lol not a fun product at all although I learned a trick to get it off.. let it dry for one day and then cover the same areas with the same damn shit and let it dry again and then both layers will peel off your skin.. you should have seen me after the por15 spill I had this summer though.. leg was black for weeks and I'm still pulling prices out of my pores as it's making all my leg hairs grow inwards lol... oh my I need to be more careful

Steve, the kreem product i use is ethanol safe. Like anything just make sure what you use is whats needed. Ive lined two other tanks with it and have had no ill effects even after 4 yrs.

Radiators shops can clean it out with acid, it would be brand new. It is best for tanks that you will be painting as they will not guarantee any damage to the paint.

Another thing to consider is I don't want to risk mucking up the paint on the tank as it is original in really great shape. However I've used ER on all my other parts and like you said Steve, it's pretty harmless to anything but rust. I'm still probably wrap the tank in cellophane for extra protection.

What do you run for gas Perry? Shell leaded fuel? I was merely stating what I have read over the years about the Kreem product breaking down. And most agreed it was an ethanol issue. Glad you had good luck with it though. I did not realize they updated the product to deal with the ethanol issues.

Great way to find any weak spots or holes just needing a little coaxing to pop through the metal. I will never use a caustic mixture on a gas tank thanks.

Glad you had good luck with it though. I did not realize they updated the product to deal with the ethanol issues. I was told it was formulated to be ethenol safe. I burn any premium i can get, whether it has ethenol or not idk, but the s2 tank is still in top nick.

You can mix Evaporust with water , it will just take a little bit longer . Evaporust is $12.00 / liter in Canada so I stretch it with 1 or 2 parts of H2O . I use epoxy resin for carbon fiber available in boat supply store for my tanks and I never had any lifting , cheap and tough .

Phenolic epoxy is very chemical resistant, and is what the oil companies line the big storage tanks with. Caswell's "Phenol novolac" is phenolic epoxy. There are other sources, and some are less expensive. I've seen generic brands on eBay in the past.
