tank relining

[Owestfall]

I'am going to derust my old 80 mns tank and reline would like to hear about pros and cons of different liners that some of you guys have tried

thanks

Well, Pro. tank liners work if you do it right and all the conditions are right when you do it.

Con. If you dont do it right the liner will come off and clog up your carbs bad.

I have used redcoat liner for years on many different tanks, I have used other liners but I like redcoat the best of the ones I have used. The only way that I would ever put a liner on a tank if if it had been boiled out at a machine shop or a radiator shop first. I would NEVER line a tank if I were to do something like electrolysis at home to remove rust or something else like that for the rust removal.

Hey Nate,

I would NEVER line a tank if I were to do something like electrolysis at home to remove rust or something else like that for the rust removal.

Don't just leave it there, tell us WHY you feel this way?

10+ years ago I got some gas tank sealant from JCW for my old special tank. I used the small metal chain technique to slosh it around inside the tank to loosen up the large flakes/bits of RUST, rinsed several times with ALCOHOL because it was cheaper and safer than ACETONE or GAS. Let it dry, then poured the liner in.....it's description said that it would work even in the presence of a small amount of rust in the tank. Sloshed around to ensure coating all surfaces...removed and plated off the fuel sender and petcock holes, drained back into QUART can, let it dry for a day, and then put all parts back on, and used it for some 9 years without any problems. NO peeling, etc.. I changed tanks to an XJ for more capacity, did the same thing with that tank with same 8 y/o can of sealant. Still going strong with that tank also!

Here's a link to what I used from JCWhitney:

It's description says it's ALCOHOL resistant, yet it says NOT for ALCOHOL
enriched? fuels, but OKAY for alcohol additives and alcohol/fuels.

I will say that the liner I got 10+ years ago was NOT specifically designed for the 10% alcohol added fuels, but has been fine. I've also used carb cleaner additives like SEA FOAM and BERRYMAN's on a regular basis with NO PROBLEMS!

A different brand called KREEM has both a KIT for derusting the tank first, etc.! I liked the stuff I used because it was for OLD car tanks with the presence of RUST in the tank! YMMV!

I wouldn't trust the liner to bond to the residue and deposits left after. I will partially retract my capitalized never from my first statement though. Prep work is key, and if you do the electrolisis and do all the prepwork well after for the liner it should still work well. The liners are ment to bond well to the small amounts of surface rust and the bare steel well, anything else and your asking for problems. So as with most things prepwork IS key and unfortunately that is where most people skimp and that is where my original statement came from.

Some radiator shops will boil out the tank and reline it. The shop here in Bowling Green does. They use that redcoat liner that natemoen talked about. I've had them coat many tanks for me. Just have to be sure its dry before you put in use. And the nice thing about the shop here is they put a warranty on it for 20 years! So it has to be some good stuff...

I'm not a big fan of tank liners either. Keep in mind that these are designed to seal a clean tank, with their primary use being to seal any pinholes that may appear after cleaning. If you get the tank clean enough and it doesn't leak, no sealer should be needed...

I used this stuff to line a SF tank. Comes complete, cleaner/rust remover/coating.
There was light rust in the tank covering about half of what I could see.
Just to prep before using the kit I filled the tank with white vinegar and left it over night.
There was no visible rust after I rinsed out the vinegar but I still followed the instructions and used all the stuff in the kit. Seems to be working well so far and was the chea... least expensive kit at the time.

I've used POR15 on my special tank after soldering a constellations worth of pinholes after cleaning it. The POR15 has an elastic quality to it and seemed like a great product. I ended up getting a great deal on a nice used tank and used that instead. I was an easy $50 into the tank rebuild and the new tank was only $75 to the door. If I had to do it over again I'd use the POR15 product that chemically interacts with the rust to help maintain some integrity in the metal before coating the tank. I'm guessing I'll use the extra tank on some future acquisition.

The only issue I had was dumping the product out. I couldn't see how to not get a build up of product around the gas filler hole as I was dumping out the extra coating.
