Review: 👍👍👍👍👍 - Have a leaky fuel tank this is stuff to use. Just follow all the instructions and it will work.
Review: Usage - I bought a gallon of cleaner degreaser, metal prep, and the tank sealer. All worked out perfectly but I did add some naphtha to help break down the varnish. I suggest that if the tank has a lot of varnish. And when you use the sealer. Use an inspection camera and add as needed to cover the tank. Conserving the product you use. It’s not cheap. But worth the money. Especially if it’s a tank you can’t find anywhere.

## Questions & Answers

**Q: Will it work on plastic tanks such as a weed eater?**
A: I used this in May 2020 on a Honda mower tank - the one that was recalled for a leaky seam. It worked. But in September 2021 it started leaking again so that was only a temporary fix in this case. Not the product's fault.

**Q: is this for external use?**
A: it can be used as an external but intended for internal. i have vast experience with por15, they make an incredible exterior rush proof coating as well.

**Q: do I need to use this on a new gas tank I bought to instal on my car?**
A: No, it is not necessary, especially considering most new cars have plastic tanks that won't rust anyway. Don't go through the hassle of? removing you're gas tank and fuel pump just for the fun of it!!

**Q: I have a toy hauler trailer it has a 40 gallon fuel tank that is full of rust would this product remove rust and seal the tank ?**
A: Hi, this will seal your tank but it won't remove the rust you'll have to use a rust remover first like evaporust or something !

### ⭐⭐⭐⭐⭐ SECOND TIME PURCHASING WORKS WONDERS...............1 year review of product.
*by D***R on 23 April 2022*

This is my second order and use of this product. I used it to coat the fuel tank on my excavator. I had a question for the manufacturer and called the company that makes it and I was actually able to speak to a real person not a computer. They were really helpful answering my questions. This is a 1 year review of this product and im still very pleased and the inside of my 69 gallon diesel tank is still perfect. I cannot vouch for gasoline tanks as I have not used it for gasoline holding cells but works great in diesel tanks
