Fixaflat Vs Slime Comparison

The Fixaflat and the Slime are both tire sealants. What they do is exactly what the name implies – you use these to refill the tire, albeit partially, so you can drive to a mechanic and get it fixed professionally. 

But do keep in mind that these tire sealants are not permanent fixes to your flat tire. They only cover the specific hole that has been punctured just so you can continue on your way to the repair shop and have the tire either replaced or repaired.

Fixaflat is easy to use. It comes in a pressurized can and does not contain aerosol. This is why in this aspect, it is not a huge issue for the environment. Moreover, you only need to spray the sealant onto the surface that needs to be sealed, and in a few minutes, it should be ready to go.

If you have never used a tire sealant in the past, you should not have any issue using Fixaflat because it is very quick, simple, and easy. It offers a quick repair to your punctured tire – until a professional gets it repaired or replaced.

Now, the can’s air pressure is enough to fill the tire up simultaneously. Therefore, you can expect 33 percent more of the sealing power required – which is better than several brands. It also boasts of an impressive 100-mile mileage allowing you to get to the mechanic for a proper replacement of the tire.

But there is one caveat. Fixaflat is only ideal for sealing a small puncture that is not bigger than 2.4 millimeters. Additionally, it is not recommended to keep driving your car even after putting this sealant to the tire when the road condition is rough and bumpy.

As for the packaging, the can is not exactly recyclable. It can also be susceptible to leaks, which is not good.

Overall, Fixaflat works great because of how easy it is to use it, and it provides you with 100 miles of mileage to take your vehicle to a mechanic for professional repair. The formula is also non-toxic and free from aerosol.

However, it is only ideal for smaller vehicles and punctures that are less than 2.4 millimeters. Also, when you need to drive your vehicle on a bumpy or rough road, it is not likely to hold too well. So, that is a huge drawback for some people.

Now, as for Slime, it is also a non-toxic sealant, but it is water-based. You can use this sealant for small vehicles, as well as off-highway types of tubeless tires. Additionally, it is a liquid sealant designed for temporary tire repairs. 

What’s impressive about Slime is the state-of-the-art Fibro Seal technology it offers. In fact, it should suffice for fixing a hole about ¼ in diameter. It also works fast, which is a big plus.

If you worry that its goo-like material may clog up your tire pressure monitoring sensor, don’t be concerned. In fact, customers who have used this product rave about the lack of blockage issue when using this sealant. 

Slime is quite inexpensive and comes in a portable packaging. It also does better when you use a compressor for inflating the tire after applying the sealant. Therefore, those who want to use this product choose to buy a complete kit for tire-repair. Plus, you need to keep in mind that there is a risk of tire damage and corrosion when you leave the sealant on the tire long enough. The adhesive substances can wreak havoc to the tire ridges.

With that in mind, Slime tire sealant is great for small vehicles such as motorcycles, jeeps, and cars. Leaks and punctures on tires can be addressed appropriately with this product, or at least until you get the tire replaced at a repair shop. 

There are no toxic odors to this sealant since it is water-based. So, there is no risk at all of blocking your tire pressure sensor. Amazingly, you can put off the tire repair for as long as two years since this sealant is highly durable. 

But there are some drawbacks to consider. You need to top off with your compressor after applying the sealant. It is also not ideal to use this product when you drive your vehicle on the highway quite frequently. There are also risks of corrosion to the tire ridges if you leave this product on your tire for a very long time.

Overall, both the Fixaflat and the Slime offer a quick fix to your punctured tire. However, there are certain differences in the way they function and perform. In terms of durability, Slime lasts longer. You can even wait for two years to get your tire replaced or repaired since Slime can keep it sealed for a long time. This is not the case with Fixaflat, and you need to go straight to a mechanic for a tire repair after you have used the sealant.

With all these things in mind, we recommend weighing the pros and cons of the two sealants to determine which one you should use in the event of a tire puncture.
