Review: Not one drop! - I've been dealing with a crack near the bottom of my fuel tank on my 79 Jeep J10 for a long time. I took the fuel down low so the crack would be dry. I cleaned it up with sandpaper and made sure it was dry. At first I thought this product was tough to knead, as it was but it's worth it. At first it seems like it's not bonding but over maybe 1 minute I could tell it was getting stickier and stickier. I got it where I needed it to be and wow was it clearly adhering. Not one drop has leaked through after setting. This is what I'll always use from now on. It shut down a full big crack completely. It is rock solid. Huge fan.
Review: Keep extra. Just incase you might need it cause its worth having. - This putty is the best. I fixed a fuel tank leak. 2 hole I've repaired. Im widowed and have to do things on my own. It really works. Follow the instructions to the T.

## Questions & Answers

**Q: Does it work on plastic tanks?**
A: bonds to clean, wet metals including aluminum and copper, to concrete and to 
plastics such as PVC and ABS.

**Q: what is the best sealer for a plastic tank**
A: 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.

**Q: I have a stripped bolt that is leaking oil, will This work?**
A: 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.

**Q: Will this repair a leak on a PLASTIC lawn mower gas tank?**
A: 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.
