There are thousands of different types of plastics and polyethelynes in use today and they continue to change every year.  Because there are so many out there, it is impossible to test all of the plastics and polyethelynes for adhesion and compatibility. Therefore, we can not completely recommend our tank sealer kits for plastic or polyethelyne tanks.

What we have found over the years is that many plastic and polyethelyne tank owners are so desperate that they have been willing to give it a try regardless of the results. The surprising thing is that most, but not all, have great results. The success is due mainly to the fact the more porous the plastic or polyethelyne, the more it leaks. But this also means the more porous the plastic, the better the gas tank sealer can stick because our Tank Sealer loves porous surfaces.

In conclusion, we can not recommend our tank sealer kits for plastic or polyethelyne fuel tanks. But, if you are desperate, you can certainly give it a shot.
