Re: Painting a plastic fuel tank with truckbed liner?
The gasoline fumes actually leach through the plastic. If the bed liner you plan to use isn't gasoline resistant it will do the same as paint. That's why the factories didn't paint those plastic tanks; because of the leaching. Eventually almost any paint or coating, unless it's formulated to be gasoline resistant will be damaged. Primers won't help, nor will sanding or surface prep. The attack is from the inside out. Even paint made for plastic, if it isn't gasoline compatable, will eventually be effected.
