1 POR-15 49216 Fuel Tank Sealer – Best Value for the Money Motorcycle Tank Sealer

Seal of approval

Up first, this Por-15 sealer. This little tin contains 8 fluid ounces of liquid. That’s more than enough for most tanks up to around 10 gallons in capacity.

A quality seal…

With a non-porous, silver film, this solution smoothly covers the inside of the tank. Working quickly, it tightly seals pinholes and seams. And it works perfectly on those rusted parts, where the gas is just starting to permeate through.

This is seriously strong stuff. Thanks to an impressive chemical formula, it remains resistant to fuels and additives. It even holds up against fuel with high alcohol content, which can be prone to eating away at the tank.

Is it easy to use?

It sure is! As long as the tank has been thoroughly cleaned, the application is a doddle. Simply pour the sealant in a steady stream, then drain off any excess as required.

Quality such as this must be expensive, right?

Not really. Sure it’s not the cheapest one around, but it’s not exactly costly. It’s tough, it does the job well, and it won’t break the bank.

However, there is one drawback with this fuel tank sealer. And it’s nothing to do with the fluid itself. The issue is with the tin. This thing is impossible to open! It isn’t a paint tin-style design that can be levered open. A pair of pliers or another tool are needed to hack our way in!

POR-15 49216 Fuel Tank Sealer

Our rating:4.5 out of 5 stars (4.5 / 5)


  • Hard and durable.
  • Fuel and alcohol resistant.
  • Compact tin.


  • Very difficult to open.

2 Kreem Products 19-103 Black Fuel Tank Liner – Best Motorcycle Tank Sealer Kit

Sealed with a kiss

Now for a motorcycle tank seal kit. This isn’t just a single bottle of sealant. Instead, we get three different bottles of product, all designed to tackle a different aspect of tank sealing.

So, what is included?

Firstly, we find a bottle of tank prep. This contains a full pint of cleaner. It’s used to wash out the tank, removing old rust and any other nasty deposits that might be hiding inside.

This is then backed up by a second bottle of prepping solution. Here we get eight ounces of conditioner. It rinses out any cleaner left behind and gets rid of lingering water.

And then, there’s the sealer itself. That bottle contains another whole pint of liquid. This is what finishes the job, sealing and bonding those tiny holes and rusted patches.

Does it work?

Yes! It really does the trick. Any pinholes are well-covered, preventing gas from leaking. It is a little time-consuming, though. The tank will probably need more than one coat. But hey, that adds an extra level of defense, giving the rider total peace of mind.

Oh, and a quick word of warning; this fuel tank sealer is pungent! Both the cleaning solution and sealant have an extremely strong smell! We’d recommend using this in a well-ventilated space; otherwise, it’s pretty eye-watering!

Kreem Products 19-103 Black Fuel Tank Liner

Our rating:4.4 out of 5 stars (4.4 / 5)


  • Three-step kit.
  • Forms a firm seal.
  • Good value for money.


  • Harsh scent.

3 Permatex 09101 Fuel Tank Repair Kit – Most Comprehensive Motorcycle Tank Sealer Kit

Seal a bargain

Next in line is another gas tank repair kit. It comes with everything needed to repair a metal tank. Included in the pack is sandpaper, a small fiberglass cloth, an alcohol pad, putty, and an epoxy resin fluid.

Quick as a flash…

This one works speedily! One applied, that resin takes just 10 minutes to harden. And after around 30 minutes, it will be fully cured, leaving the bike ready for refilling.

So that means we need to move quickly. Once it’s been mixed, the sealer quickly becomes tricky to apply. Have everything in place before beginning this job; otherwise, it’s easy to end up wasting half of the liquid.

Is it strong enough?

It is. It forms a sturdy shell over most cracks and rusted holes. Tough and supportive, it traps the gas in and preventing new leaks from forming.

But it doesn’t last as long as we’d like. Remember that putty we mentioned earlier? Over time, it begins to dry up and crumble. While it will endure for a few months, after that we might run into problems.

So, it’s a temporary fix?

Yes. It works brilliantly for short periods of time. As a make-shift repair, it’s a fantastic choice until we have time to get the job done properly.

There’s a lot to like here! It’s so convenient having everything we need in one handy kit. And at a very reasonable price, too.

Permatex 09101 Fuel Tank Repair Kit

Our rating:4.3 out of 5 stars (4.3 / 5)


  • Fast-acting.
  • All-in-one product.
  • Easy on the purse strings.


  • Lacks durability.
  • Can be too quick to harden if you are not fully prepared.

4 Seal-All 380112 Contact Adhesive and Sealant – Best Budget Motorcycle Tank Sealer

Seal the deal

At just two fluid ounces, the next product in our search for the best sealer for motorcycle tanks is this tiny tube of paste. Here, we get a clear, sticky substance that plugs up holes and seals off seams.

And it’s not just a fuel tank sealer! It works as a glue, too. It strongly bonds most materials, with an almost impenetrable hold.

How does it work?

This one couldn’t be easier. All we need to do is make sure the area is clean and dry, then apply the clear paste. Wait a few minutes, and there we have it!

And we do mean a few minutes. This acts fast. After just three minutes, it will be completely hardened and fully cured within half an hour.

What other qualities does it have?

It’s water-proof from the second it is applied. Even when still wet, it repels moisture. Plus, it’s resistant to oil, alcohol, and of course gasoline, so we shouldn’t find any new leaks popping up.

This sounds too good to be true! It is?

It’s difficult to find a downside! But we should say that the contents may harden in the tube over time. And we don’t get any extras included, such as cleaning fluid or sandpaper.

Seal-All 380112 Contact Adhesive and Sealant

Our rating:4.6 out of 5 stars (4.6 / 5)


  • Wallet-friendly price.
  • Straightforward and simple to use.
  • Durable.


  • Small volume.
  • Sealer only.

But at this price, do we really care?

5 J-B Weld 8217 TankWeld Gas Tank Repair – Most Versatile Motorcycle Tank Sealer

All sealed up

The final product in our review is this two-part stick. Weighing in at just one-ounce, this a diminutive option. It’s meant for one-time use, not sitting on the garage shelf in a tin, ready when needed.

How is it used?

Take the two separate sticks and knead them together by hand. This forms a kind of putty, which can then be shaped to fit the hole. Once stuck in place, the putty will harden in just five minutes and be completely cured in under an hour.

But beware! It starts to solidify as soon as mixing begins. Prepare to work quickly, or it gets too hard to form into the correct shape.

After that, we can do anything we want! We can leave it as it is or sand it down. It could even be painted over if its dark gray hues don’t match the rest of the bike!

That sounds easy!

It is! This is a really straightforward product. And it’s multi-purpose, too, as it can be used on stainless steel, aluminum, iron, or even bronze.

And the chemical formula here is impressive. It fights off moisture, stopping rain from entering the tank. Plus, it’s resistant to most harsh chemicals, such as hydraulic fluids or gasoline.

What’s the catch?

Not only is this a one-time product, but it’s also a temporary one as well. It’s not very long-lasting. This one is best for patching a motorcycle up, not for a permanent repair.

So, there are ups and downs. But there are far more ups! This is a handy little item and an awesome way to end our hunt for the very best quality motorcycle tank sealers you can buy.

  • Not a long-term solution.
  • Hardens too quickly for slower users.

Best Motorcycle Tank Sealer Buying Guide

Best Motorcycle Tank Sealer Review

Selecting the best tank sealer for your motorcycle can be a daunting task. There are so many options to choose from. So, what should we look for when picking the best product for our ride?

Let’s go through the process of sealing a tank…

It’s not just a case of slapping on some glue. First, the gas tank needs to be emptied and cleaned to get rid of any rust, dirt, or grime. Then it needs to be thoroughly dried. Sealant won’t bond on a wet surface. So ensure that the metal doesn’t retain any moisture for a tight hold.

That means that a fuel tank sealer kit can be an awesome option. Something that includes everything we need for repairing the fuel vessel. A cleaning fluid would be fantastic, as would sandpaper or rubbing cloths.

A long-lasting solution

After that, the most important thing has to be durability. This adhesive needs to hold. It should be tough and enduring and avoid flaking over time.

Of course, we might want a product that can be used on the go. A temporary, fast-acting glue can be incredibly convenient if we run into trouble when out on the road. If that’s the case, it needs to be simple to use and easily transportable too.

What qualities should it have?

Of course, it needs to stop gas from leaking, but what else? A high level of water and chemical resistance is paramount. It has to prevent moisture from seeping in, as well as holding up against erosion from harsh chemicals.

Speaking of chemicals, remember that not all sealers are suitable for every material. Most of the products in this review are not plastic gas tank sealers. Check that the option you pick is suitable for your tank; otherwise, you might find it eating through the walls!


And finally, let’s talk about price. It’s always tempting to go for the cheapest option! But the cheapest rarely equals the best. With tank sealer, we usually get what we pay for, so choose the product that offers the most bang for your buck.

Wow! There’s so much to consider! But hopefully, we’ve given you a better idea of what to look for when selecting the best motorbike tank sealer for your ride.

But, what’s the Best Motorcycle Tank Sealer?

Picking a winner wasn’t easy! We saw some amazing contenders in this review. But in the end, the best had to be the…

Kreem Products 19-103 Black Fuel Tank Liner

We loved that this came with cleaner and conditioner. Not only does it save money, but it’s also more convenient than going out and buying separate bottles of solution. Combined with its fabulous chemical resistance and tight sealing properties, this product just about edged ahead of the others.

Add its incredible durability into the mix, and we have an almost perfect choice. Just remember to use it in a well-ventilated space; the fumes are not pleasant!

So, happy riding, folks!
