thanks mate!!
I spoke to the guy and I am confirmed a 100 percent that this product is HIPS.
He does seem to know a little of what he is talking about, not only he confirmed it but he gave me a quick lesson on ABS.
It seems that the rolls we get here in Australia available to small businesses is Styrene (hips) , these sheets are coated with a layer of GP Styrene, which is a no body film of supergloss clear, to one side of the sheet.
This film is easily removed by fine sandpaper and virtually has no body to it.
The EVERGREEN stuff you are able to get in the US , we do not import that in large qtys and sizes, the most common styrene here is coated on one side with clear.
He also explained that ABS is a different colour and is thicker and dense in itself as opposed to styrene and as you can see , light does not go through styrene, he actually made me a pull of ABS to show here.

The reason why the armour plating has the gloss on the outside , is because he figured that the most surface area to glue on the armour plating was the rear, so the head and upper had will have the matt side up.
All armor plating is done , I will update the sale thread.
hope this clarifies the material side of things

further on the build, I have a sample mock up of the side Trapezoids looking indents , these will also be vacformed , a new CNC mold will be made for these , should have a finished one shortly.
The head (upper and lower domes) are now being reduced in size by 3mm, now that the armour plating has been finished , also will have them shortly.
