## Features

- ✅ WHY CHOOSE POR-15 FUEL TANK SEALER? POR-15 Tank Sealer is specifically formulated to provide a permanent seal with superior strength and resistance to all fuels, including the new Stage II fuels which have a high alcohol content.
- ✅ STOP RUST - POR-15 is the gold standard in rust prevention, and our Fuel Tank Sealer is no exception. Formulated and developed in our laboratories due to the demand for a high-tech sealer impervious to all fuels, POR-15 is essential in preventing rust and corrosion for long lasting results.
- ✅ PREP FOR SUCCESS - Drain all fuel from tank, remove tank from vehicle, and clean out tank. All fuel tanks are dirty and have to be cleaned out before sealing. If you try to seal a tank without cleaning it first, the new coating will fail, because Tank Sealer won’t stick to gum and varnish. After taking preliminary steps for cleaning and prep, use as directed for an excellent finish.
- ✅ WHEN DO I NEED THIS? – POR-15 Fuel tank sealer is perfect for automotive restoration. Renew your car, truck, or motorcycle fuel tank through our simple, single application coating. Allow proper time to cure for impervious protection from fuel, alcohol, corrosion and rust.
- ✅ OUR SATISFACTION COMMITMENT - At POR-15 we strive to bring the ultimate in rust prevention. Known for the unbeatable 3-step stop rust system, POR-15 is trusted by DIY & Professionals. We are committed to innovation, quality control, and excellent customer service. If you are not satisfied, let us know & we’ll do everything we can to make it right!

## Questions & Answers

**Q: what size tank will a pint seal?**
A: Easily an 18-gallon tank - I had plenty left over with mine.  I could probably have sealed even a 20 to 22-gallon tank.

**Q: I'm having my tank powder coated after I seal it. Will this stuff be ok baking at 400 degrees to cure powder or should I use after its painted**
A: I would recommend powder coating first then applying the sealant! The sealant has a heat limit of about 400 degrees. Although I would clean the inside then wait till after the powder coating to use the metal prep & sealant.

**Q: Could you use this to protect and seal the outside of a cars rusted gas tank?**
A: Very unlikely to seal a tank from the outside. Use a fiberglass tank repair from an automotive store. Even then...not too likely. This would be really expensive paint for just cosmetic purposes.

**Q: Will this work to seal plastic gas tanks**
A: Hi Renee! If You Have A Plastic Tank That Is Leaking I Would Suggest A Soldering Gun (Heat) To Repair Leak/Crack. If Your Tank Is Nasty Inside I Would Suggest A Commercial Cleaning Product. POR 15 Needs A Rough Surface To Adhere To. I Would Not Suggest Using POR15 On A Plastic Tank. Good Luck!
