Hello guys, my first time on here. I've a 650 litre upright tank, fitted up against the bulkhead. With hindsight I would have done things differently, but my only option was to put it against the bulkhead. I'm taking it out this weekend to paint the van floor with protectacote, and then put it back. Is there any tips on what to put between tank and bulkhead to stop it from squeaking when I'm driving? Thanks in advance
