Tank Liner

Solid Labor · Feb 12, 2011

I have a '49 H with a 20 gal fuel tank. Had rust in the the bottom of the tank. Cleaned it out and put two qts cans of liner in it and drained 1 1/2 qts out. It looks like it has a very thin coat after it dryed, so I put about 3/4 of a qt in the tank for a second coat of liner in the tank and drained about 1/8 of a qt out. But, it looks like it all stuck to the bottom out the tank and zero got on the sides or top. And my second question is do I leave it or re-clean the tank and redo the tank or leave it as is because it OK that way.

You should have left it alone after the first coat. It don't have to be very thick as it forms a thin membrane around the tank and as long as it's covered completely it will be fine. As far as the second coat it should be fine as long as you let it dry good before putting anything in the tank.

Thanks for the reply. I figure one coat would have been OK. But, I just was not happy with the lining, so put the second one. For the drying, it will be 10 days before I can put the tank back on.

When you drained the liner did you dump it back in the original cans or did you put it in a new container?
I just want to be sure I know how I want to save the excess so I don't waste it.

Also, did you do yours outside? My supplier said he doesn't like to let the stuff freeze, but he also said it STINKS bad so be sure I do it outside. It is 31 now and supposed to get to 45 today. I might wait until after church and do it outside. It should be totally above freezing my then.

I don't think the second coat was a bad idea at all. Step 12 of my Red-Kote reads

12. If the leaks were severe or not all rust was removed, it may be necessary to use a second coat after the first coat has dried completely.

Unless you got in a hurry, I don' think you hurt anything.

I put it back in the original cans. I live in South Texas. The first coat was done at 65 deg @noon, 28 degs at night and dryed for 3 days. The second coat was 62 degs @noon and 45 deg last night. It seamed to me that the second time the liner was a lot thicker when I poured it. I did it all outside and put it in the shop at night. If I was doing it again. I pour the liner in and every 5 mins, I roll the tank 8 to 10 times around for a good first coat. Then throw the drain liner away. The whole key is a very clean work area.

Mine didn't seam near as thick as I wanted it either. I was told it would be almost as thick as a fruit rollup and have the same texture. Not even close.
The can that I poured it from had that texture when finished, but the fuel tank has NOTHING on it. Maybe I just can't see it as good. The fuel tank is shiny silver and the can was white. That should make a huge difference.

Yes, Your right about the thickness. The first coat is very thin and that is why I put on the second coat and it all stuck to the bottom of the tank.
