any benefits...


help me understand

Me just being cautious. You never know where pics posted on the internets might end up.

I have added personalised plates since this photo, so it wouldn't have mattered much anyway.

Follow up on the jerry can: I keep mine full of diesel most of the time and have noticed the paint is rubbing off the can where it contacts the rubber strip on the back of the Perentie. When it's empty, I flip it around, to make for easier filling and to remind me it's empty. Much less paint rubbed off on the "empty" side. Prob. because it spends less time this way more than anything else.

Underside looks ok. Dunno if a rubber mat underneath would actually increase wear??

I was at a MV display recently. One of the jerry cans on one of the vehicles sprung a leak. It was sitting on rubber.
I'm told metal on rubber wears quicker than metal on metal. I don't know if it is true but I suspect it may be.
Where are Jamie and Adam when you need them?

Yep depending on what the rubber sheet is that is used the surface can be very hard, and the material can be quite rigid in the plane of it's thickness e.g. rubber insertion used for pipework flanges; it compresses only a little at the surface for sealing but is quite rigid under further compression. I could certainly see where the base of a steel jerry could/would wear on the surface of a product like insertion rubber over time.


I think a foam material such as the polyethylene foam used as concrete joint filler strip would be better and it's what I'll be plumping for; it is available in a range of thicknesses, it is compressible (the amount of compressibility being dependant on the type/grade), and it has a smooth external face each side as a wearing surface. There's probably other similar material out there - I'm just familiar with this product as my background is civil design/construction.


Yeah - I could see this on Mythbusters.......

But what is its resistance to diesel like?

I have sheets of insertion rubber that I cut stuff from. don't normally have problems with it.


I replaced a fire truck tank and it had been packed selected size sheets of pollystyrene. the sheets on the bottom had been as heavy as light wood. with little compaction.


Have had to do recall and reworks because the rubber used attacked any moist metal. was told it was PH issue. sometimes it was only cured by painting a protective surface--very thick and nice shades of rust brown.
