## Description

Features and Benefits: Cures on wet and dry surfaces Easy to use Great to repair gas tanks, water tanks, and radiators Cures in 1 hour Made In USA

Review: It Works - Works great. When mixing the product for a "uniform color"....another way to determine when its ready is you will notice a very distinct smell of dead rats. As I was kneeding it with my fingers I checked my entire backyard looking for a decomposing rodent, only to find out it was the mixture within my hands. Good stuff tho. 20 yr old generator tank that replacements no longer exist, this sealed it up nicely.
Review: Great results - Worked excellently. Sealed a gas tank leak immediately and has remained sealed. Adheres extremely well quickly hardens and stays attached. Sealed leak

## Questions & Answers

**Q: Will it bind to plastic? The top of my fuel pump housing has a small chip, and its now leaking fumes. How well will this patch up the plastic housing?**
A: I used this to seal a hole chewed (by a squirrel) in the top of my Craftsman snowblower fuel tank.  It bonded to the plastic tank and sealed it completely.

**Q: Can i use this on a pressured gas line?**
A: I would not recommend this due to safety reasons. Best to change the line with an approved replacement.

**Q: Does the gas tank have to be completely empty and dry? I have a tiny hole in the bottom of a metal gas tank.**
A: For best results you want to make sure the gas tank is totally empty and totally dry so that the epoxy can adhere to the metal if it's wet it won't adhere to it well at all

**Q: Will a magnet stick to the cured epoxy?**
A: Was very easy to attach in place but nemember to scratch surface to bare metal, then it stck very well, stay in place and seal the hole. Very easy to use, I like it.
