## Description

POR-15 49204 Fuel Tank Sealer 32 fl oz

Review: BEST Tank Sealer - POR15 products need no introducing . This can easily did my 2 gallon Motocycle tank, you'll need to strip and fully de rust the tank first or IT WON'T WORK . Needs serious mixing, the bottom of the can was the separated out part, I tried shaking it a while to no avail so I used an old CLEAN large flat bladed screwdriver to slowly turn and turn it until the colors were fully mixed, takes a goodly long while . Once opened the stuff needs to be used soon so DO NOT OPEN THE CAN UNTIL THE TANK IS DE RUSTED AND YOU'RE READY . I used a medium sized plastic funnel to pour it in then I capped the tank and began rotating it to ensure the mix flows into every corner and crevice ~ this is not a job you can rush . After making sure it had fully coated the inside of the tank I cleaned up the stirring screwdriver and funnel, it's easy to do if the stuff is still wet, once it dries it's *PERMANENT* so watch there you're working as it WILL NOT COME OFF EVER . floor, driveway, clothes, etc. . if the tank you're working on has any pinholes, be sure to tape them up first, this stuff is amazing and plugs BB sized pin holes easily . Don't forget to follow the instructions to the letter and remember to keep tuning and tipping the tank so the mix covers all crevices and the inside of the top too . I polish then wax the tank first so any droplets I might spill are easy to wipe off right away . I also tape around the filler neck with blue painter's tape because I'm extra cautious . I used this product in a 'Hail Mary' to save a 40 year old badly rusted and leaky Motocycle tank, I hope in time I'll find another but fr now it works fine, the ethanol laced fuel doesn't seem to bother it . I imagine I could have done up to a 5 gallon tank . -Nate
Review: Working great so far, I recommend this product - I used this tiny can for a small very rusty flaky gas tank on my 30 year old Mclane edger that kept plugging up the carburetor. I didn't purchase the recommended cleaner or metal prep. I used a bottle of rustoleum rust stripper and a bunch of nuts and bolts to clean the inside of the metal gas tank. Then I rinsed it with water and let it completely dry. After a couple of days of drying it had formed a thin layer of rust, but as I read, a little rust is good for por-15 work. Por-15 runs like watery paint and coats metal, creating a protective hard layer, preventing metal from oxidation. I think there are 4 main colors of por-15. The container I bought says gray on the label, but it actually is a metallic silver color. I am ok with any color since its inside a gas tank. I followed the directions, and poured a half a cup in, sealed all the holes, and shook it for several minutes to coat all the surfaces inside. Then I emptied the excess back into the por-15 can. I let it dry for a half hour and used a tissue to carefully soak up the excess in the fuel tank without wiping away the newly created layer. (Use latex gloves or other). I waited a while for it to become a hard but slightly tacky surface before I created a second coat. But not too soon to trap the curing process of the first layer. Then several days later after the 2 coat curing process had finished, and most of the smell subsided, I was able to reassemble the machine and give it a test. You can make 1 layer or several layers. I chose 2. The por-15 can is small, but I only used maybe 2-3 tablespoons to make 2 coats in the fuel tank after pouring the excess back. A little bit goes a long way. I still have almost all of the liquid in the can which is awesome. Its been about 1 month now and after several uses of my machine, the inside of the fuel tank still looks new. With the reflective silver coating in the tank, I can now use a flashlight to peer in to see how dirty the fuel is that Im using and see particles settled at the bottom. Hopefully this fuel tank now lasts for many years. It gave a 30 year old very rusty fuel tank and machine new life. My edger with a briggs engine runs excellent. So far its a really great product and Im very happy with it. It was worth the cost despite the size of the can because of how small the amount of liquid is used. It probably could be used on a dozen mower sized gas tanks or a few motorcycle tanks before it runs out. The por-15 can doesn't need to be any larger. I would recommend this product.

## 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.
- ✅ PERMANENT SEAL - 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 meet the demand for a high-tech sealer impervious to all fuels. POR-15 is essential for long lasting results.
- ✅ APPLICATION - 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. Use both our Cleaner Degreaser and Metal Prep before applying sealer. 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.
- ✅ 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.
- ✅ COVERAGE - Quart (32 fl oz) can is enough to coat the inside of a 25 gallon 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 !

### ⭐⭐⭐⭐⭐ Works
*by G***C on April 26, 2026*

I had a predator generator from Harbor Freight. It had a steel gas tank that after several years, rusted and it was a never ending problem keeping the rust at bay. There was no option for a plastic or aluminum gas tank. I ordered this tank sealer, followed the directions and was very pleased with the results. It coats the tank in a coating that is compatible with gas. If I had kept the generator and not upgraded, I'm sure that my rust problem would have been solved. It's a bit expensive but it works as described.
