So I wanted to protect the tray without applying a permanent product. And those plastic ute liners scratch. So I found an alternative. So here is what I did.
I took a trip to Bunnings to see what materials they had. I chose some indoor utility carpet, comes 2m wide and $33/lm( i got 3m of it).
I chose this because plain old marine carpet is very scratchy, the indoor carpet is made pretty much the same but it is a lot softer and wont scratch much. Just to be on the safe side I also got some of the non slip mesh, to put on the bottom underneath the carpet so it wouldn't slip or scratch. It comes 1.2m wide $12/lm.
When the guy was cutting it, he had the battery operated rotary cutter. So I picked myself up one while I was there. It is a Bosch Xeo ($60). Pretty good little thing, but doesn't cut tight corners very well... if at all.
I also picked up a 5m roll of sticky/hook velcro (sticky on one side, hooks on the other.) to keep the carpet in place.
I did do a template with rough measurements on a piece of paper before hand to make sure I could cut every piece out of the 2x3m carpet I bought.
So it was just a matter of lying an oversize piece on each section and cutting pushing and poking to fit. It is a bit fiddly around the wheel arches and you have to do a few slits to make it fit round the curves properly. And damn is it hard to cut a straight line.....
Only Before photo I have of the tray
Progress
Finished
Velcro Strip along top of tailgate and a few at the bottom.
It just sits tucked up under the top edge.
Just to show how it is layered.
Took about 5 hours or so, but I think it is worth it.
Question/Comment's welcome.
