Top 5 Best Gas Tank Repair Kits
What Is a Gas Tank Repair Kit?
With time, anything that is metal will eventually see its share of rust and corrosion.
This is especially true when it comes to vehicle components that are exposed to their fair share of road salt and grime.
With time, fuel tanks begin to rust, leaving behind leaks of varying degrees.
Additionally, an ill-timed collision with road debris can leave your gas tank on the losing end of a fight that it can’t possibly win.
The damage left behind all too often results in an aggravating fuel tank leak.
A fuel leak of any kind requires immediate attention. Gasoline is highly volatile, and will quickly combust upon finding an ignition source.
This can quickly turn your prized ride into a blazing inferno.
Not only does this scenario irreparably damage your vehicle, but it is a life or death matter as well.
When a leak is discovered, you have one of two choices. Replace the gas tank, or attempt to repair it.
While replacing the leaking gas tank altogether is indeed the best route when possible, doing so is not always affordable for some.
Gas tank replacement costs can quickly reach the $1000 mark on some vehicles, leaving a vehicle’s owner with an immense case of sticker shock.
So...on to plan two, gas tank repair. Gas tank repair kits come in several different varieties.
However, all of which seek to accomplish the same goal. The application of the chemicals within these kits cleans and repairs the damaged segment of the gas tank, saving you time and money along the way.
In most cases, a single application is all that is needed to stop the pesky leak in its tracks.
A repair of this nature can generally be completed at a fraction of the cost of a gas tank replacement and is considered safe when done by a knowledgeable individual.

How Do Gas Tank Repair Kits Work?
A gas tank repair kit works by sealing the damaged portion of the tank from the outside. This eliminates the need for dangerous welding and other more invasive means of repair.
This process often begins by preparing the surface that is to be repaired.
For optimum results, any grease, oil, or other foreign substances need to be removed in their entirety.
Additionally, a light sanding of rusted surfaces assists the adhesion process between the tank’s shell and the bonding agent.
With the surface prepped, the epoxy provided with the repair kit can be readied. In some cases, this requires the mixing of two individual chemicals.
In other cases, the bonding agent will be a single part epoxy that begins setting up when exposed to air.
You will now coat the affected area to cover any visible damage. It is often beneficial to coat slightly beyond the leaking surface in every direction.
This remedies any secondary leaks that might have gone unnoticed, due to the volume of the primary leak.
You will now allow this coating to cure. The time that this will take differs by product.
Some such products cure in as little as two hours, while others can take as long as 18-24 hours.
Regardless, it is very important to follow the directions found on the product’s packaging. A failure to heed these directions can lead to a leak and potential fire hazard. For more on the hazards of gas leaks, read this article.
After curing is complete, the tank should be carefully looked over for the presence of any continual leakage.
Even after your vehicle is back on the road, it is important to periodically inspect your gas tank to ensure that the repair is still viable.
NOTE: If you do not feel comfortable with the idea of fixing your gas tank, or feel unsure of your work at any time during the process, seek professional repair. The prior instructions serve solely to give a general overview of gas tank repair with external epoxies and are not intended to take the place of manufacturer instructions.
