Does it work on plastic tanks?

bonds to clean, wet metals including aluminum and copper, to concrete and to plastics such as PVC and ABS.

what is the best sealer for a plastic tank

The new formula SealAll DOES NOT SEAL GAS LEAKS. The old product worked great and used it many times. The new product is only gasoline resistant and breaks down in only a couple of days.

I have a stripped bolt that is leaking oil, will This work?

The stuff I got was so hard it could not be mixed together. If it was soft enough to actually mix like you need to, you could probably put it on the bolt and screw it in but you would not get it back out.

Will this repair a leak on a PLASTIC lawn mower gas tank?

No. I followed the directions exactly to try to stop a leak in a plastic gas tank on a riding mower. The leak returned in just a few weeks.
