I've got a '72 Ski-doo Olympic and the gas tank has small hairline cracks in it where the gas slowly drips out. I tried roughing up the surface and patching it with PL premium, and then apoxy but both times they just peeled off when dry. It there any liner or patch material anyone knows of that will work?

I'm assuming it's made of some type of metal. Take it off and take it to a welder. Don't waste your time trying to cobble it with epoxy and stuff like that. I sure as heck wouldn't want my gastank to start leaking in the middle of a ride because I did't have it fixed correctly.

Rough it up, clean real good and try regular JB Weld, worked great on my artic cat, do two applications, not one big glob.

I would and see if you have someone local that does plastic welding and also maybe just check on craigslist or ebay and just get a new(used) tank!? May not cost that much[dunno]

ya, there's a tank liner i use on tractors (and sleds), it's called red-cote i buy it from a farm supply company, i think its called value-built. just search red-cote tank liner, this stuff is the BEST tank liner you can get

I can't believe no has suggested ducktape lol. by the way i'm not suggesting it.

Isn't there some kind of liquid that you can put in the tank and rotate it so that it gets all the sides and leaves a thin seal over in inside?

I fixed my old '72 elan plastic tank by welding it myself. I used an electric soldering iron and just worked it back and forth along the cracks till it made a nice bead as in welding metal. Worked fine till I junked the sled-

Plastic welding would be your best option. You can do it yourself but the best result would be by a professional and it will last forever.
