Review: Excellent Product - Received 4 days early before delivery date Thank You Klamp, used POR - 15 for RE TB 350x it took 3 to 4 days to dry completely. Fuel tank from RE does not coat anti rust from inside so it gets rusty because of ethanol mixed with petrol. But keep everything ready before opening the can.
Review: Good product - Expensive However its a very good product. Very satisfied withthecoating it did for my Yamaha RD 350 petrol tank

## 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 !

### ⭐⭐⭐⭐⭐ AMAZING !
*by S***E on 11 August 2024*

This tank sealer is a life saver for the bike's fuel tank, a few months ago my 20yr old bike's fuel tank started developing pin holes & leaking petrol. I got the entire tank first welded & sealed properly & cleaned it from the inside out. I had painted the new tank & once it arrived I poured the entire POR15 inside the tank & made sure the paint touches every part of the tank on the inside surface. The tank was then put to rest for the next 48hrs & WOW ! The results were amazing.. Luv this product.
