Ok another update to the tray I hate the look of silver of the alloy tray that's why I had it powder coated, but it left the tray silver and it was bugging the he'll out of me.
So options I had was to paint it black but I figured it would ware and look like poo.
So option 2 was rubber mate don't like that as it traps dirt and water underneath.
So option 3 was spray on liner I liked that option the best so I had to track down A do it yourself kit as I like doing most things myself and what I found was a kit called a raptor kit by upol.
A few things to do for prep I had to etch prime the alloy and rough up the powder coat then wipe it all down with wax and grease remover.
To apply it you can roll it or spray it on with a underbody spray gun I chose to spray it.
Here is the end result
