dells68 7,498 #2 Posted March 27, 2018 I bought a gas tank kit from POR15 to use in a VW. It worked great and is still fine about 8 years later. 1 Share this post Link to post Share on other sites

JPWH 6,256 #5 Posted March 27, 2018 I used POR 15 on 2 gas tanks and a hydraulic tank. A 1/2 pint will easily do 2 854 tanks. 1 Share this post Link to post Share on other sites
KC9KAS 4,744 #6 Posted March 27, 2018 Personally I haven't had to treat a tank, but most things I have read suggest the POR 15! Share this post Link to post Share on other sites
moe1965 752 #7 Posted March 28, 2018 Red Kote. You can get it on eBay or direct from the manufacture . Share this post Link to post Share on other sites
Pollack Pete 2,273 #8 Posted March 28, 2018 POR-15 has my vote.Been using their paints and coatings for years with nothing but excellent results.Pricey,but you get what you pay for. 1 Share this post Link to post Share on other sites
Jerry77 1,218 #9 Posted March 28, 2018 I used the kits you get from Eastwood....used them on old cars that I restored....worked good and lasted.. 1 Share this post Link to post Share on other sites
Pinball 30 #10 Posted March 28, 2018 Red Kote all the way. I have used it on a lot of motorcycle tanks and had NO problems at all. The nice thing is you can buy it at O'Reilly's Auto Parts. If you were to mess it up Red Kote can be removed as for POR-15 and Kreem I don't believe you can. My 2 cents. Share this post Link to post Share on other sites

pfrederi 18,334 #12 Posted March 28, 2018 Eastwood kit Did teh tank on my 1953 M-37 abut 20 years ago. still have clean gas. Also did the tank on my Case VAC tractor (1951) about 12 years ago. She had some seepage. Eastwood treatment stopped it and has held just fine ever since. Still looks nice inside. 1 Share this post Link to post Share on other sites
ebinmaine 70,769 #13 Posted March 28, 2018 Thank you folks for all your responses. I had a busy day yesterday and haven't had time to look much but it seems lots of people prefer por-15. One question Pops to mind this morning. Are any or all of these products a lighter color so you can look in the tank and see how much gas is in there? None of mine have fuel gauges...

oliver2-44 10,370 #15 Posted March 28, 2018 Red Glyptal Insulating Enamel Paint also works well if you have access to it. We have a lot of old oil reservoirs coated with it at work. Been on there for many many yearly Share this post Link to post Share on other sites
richmondred01 2,289 #16 Posted March 28, 2018 (edited) POR15 or Bill Hirsh sell some very good products. I’ve used his stuff in several of my vintage cars and farmalls. clean the tank. I put several small rocks in the tank (count them as you are putting them in....ask me why) The shake the tank with the rocks which will remove the scale. Blow it out with air and repeat several times. rinse well with water and let it dry for several days. when it’s dry use the aforementioned products. All the best....

Joshn569 273 #21 Posted March 28, 2018 Check out caswell fuel tank epoxy sealer. It coats right over any rust and it ethanol safe. Ive had great succsess on motorcycle tanks both metal rusty ones and new plastic ones (the ethanol was causing plastic tanks to expand and warp and this product stopped that from happining) 1 Share this post Link to post Share on other sites
