I've been reading this morning about Red Kote, their web site says 1 qt. per 15 gallon tank.
Dave Bennett and I were thinking at least 2 qts in a cub tank.
Anyone used any of this before ?
Is one qt. enough ?
I know a few who have sent their tanks out to have this done but I'd rather do it myself. I have very little rust in the bottom, but after air brushing the underside I see some pin holes coming through.

Yogie- I haven't used Red Kote but I'd pay attention to their directions. I think 1 qt. would be plenty for a cub tank. If you get the stuff on too thick you'll have peeling and adhesion problems.

I've used Red Kote, and it has worked out really well. Some of you may remember the day that Kelley scared me to death brazing the fuel tank on my 54 Cub. We really had to do some patching on it as it looked like it had been crushed and ripped open at some point. After Kelley's brazing, and some work at the body shop I decided that I wanted a little extra insurance that I wasn't going to have a leak. I went and got a qt. of Red Kote from the local parts store. I followed the directions and when I poured out the excess, there was 1/2 quart back in the can. I waited the recommended time and then put in a second coat (just for my own piece of mind, I don't think it was really necessary). That pretty well finished off the quart. If you use it, be sure to let it dry an extra long time. The longer the better. The gas turned red in the sediment bowl a few times, but I did this in May of last year, and it has had the tank filled up several times with out a leak. I was pleased enough with it, that there is a second qt. in the basement just in case.

I have used the POR 15 gas tank treatment product - seemed to work well but have not had it in use long enuf to know how it w/hold up. At least no plugged gas filters yet! Dusty B

One Qt. will be enough, Yogie. As Chad said, about half of it will be poured back out and you can do as he did with a second coat. (a peace of mind thing) And yes, it does take a long time to thoroughly cure. Set it outside in the warm sun every chance you get, cap off of course.

i used red cote in the tank on Blackie about 8 years ago and there is no problems to date.
and have used it several times on other cubs i no longer have .
I don't remember the correct instructions off the can.
I know how i do it and it works .
make sure there is NO moisture in it i use MEK Laq. thinner to evaporate any moisture from the water washing.
I also use the MEK to cut the red cote so it is thin enough to be able to rotate the tank and get a good coating all over the inside the MEK also helps in the drying aqnd curing .
let it dry a week in the warm hot sun then recoat a second time let it cure a couple weeks before you put gas in it .
you will want to do the rd coating before you do any painting onthe tank as it can e a messy job.

I have been restoring antique motorcycles for years as well as tractors, with some of the modern gas i have found the red kote does not hold up, por 15 has always sealed, fixed all problems and holds up for ever to date, in the motorcycle world we pre seal every tank with it even if it does not have a problem or if it is new, it costs to much in time and labor to go back and start over again

Thanks to everyone... This is the tank on Gray Cub's project tractor and it will be a good 8 weeks before it's used so the waiting time is no problem. I'll call around tomorrow and see what I can find.

I can't answer your question about the "Red Coat" tank sealer. However, I do have some experience with the POR15 tank sealer. I have done two. Both times I followed their instructions to the letter and made sure they were dry. I have had no problems with them in the past five years. I can't remember the exact amount for each tank but it was whatever they recommended and had some to drain out onto the ground. It stayed intact with dirt on it for four years and I still had to scrape the sand off it. With POR15 you CAN NOT put it back into the can and use for a second coat later. However, if done according to the instructions there will not be a need for a second coat. Just my experience.

i cant answer to the how to, but can answer to the red kote, all my demos have it done, $50, i get the tanks boiled in muratic acid and coated. Just wish i didnt have to drive an hour to get there.
*edit* forgot to say, several years into to it, no problems on any of my tanks, gas is crstal clean coming out. Highly recommend this process on all tanks.

I put Red-Kote in two tractor fuel tanks 5 or 6 years ago - no problem.
Make sure the inside of the tank is as clean as possible and DRY - Bone dry before before putting in the Red-Kote.
You need to let the Red-Kote cure. The cure may take several days depending on temperature and humidity. If you can smell the Red-Kote - not cured yet. Biggest thing is to fully cure the Red-Kote before putting fuel in the tank.
I used a shop vac on exhaust to dry the tanks and to speed up the cure time.

I've used liquid steel for most gas tank repairs. If you have holes i would use a filler first like liquid steel then red kote it on the inside to be sure its fixed. But not all of these products like our new modern gas too. How about taking it to a radiator shop were they can sink it in the test tank and braze it or put a steel patch and braze that into place.
With using liquid steel i just sand down the area to bare metal and apply it.
