I have a collection of vintage KTM dirt bikes. These bikes came with plastic tanks. Over time the tanks, which were originally white, have become discolored.
The fuel in them has penetrating and turned them a yellow color. I can paint the tanks but need a sealant to prevent the fumes from inside the tank peeling the paint. Do you think your product would seal the inside of a plastic gas tank? I have spare tanks so I could try if you think your product will adhere to plastic.

Plastic Tanks; long story short is there are thousands of different types of plastics in use today and they continue to change every year so as you can imagine it is impossible to test them all for adhesion and compatibility. Hence we do not recommend our kits for plastic tanks. But where does this leave the poor leaking plastic tank owner? With new tanks costing many hundreds of dollars - if you can buy one. What we have found over the years is many plastic 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, not all, have good results. This is due mainly to the fact the more porous the plastic the more it leaks. But this also means the more porous the plastic, the better the gas tank sealer can stick! Because it loves a porous surface even plastic.
So we do not recommend our kits for plastic fuel tanks. But, do people buy them for that application? Yes they do. But we do not and can not recommend its use or guarantee the results (you are on your own). So if you want to give it a try call us but if you want a guarantee we can’t help you
