Before I go at it like a bull in a China shop what will restore the faded hood and rear window?

What material is the hood ? and how bad is the rear screen, is it just misted ?

The roof looks like it needs re-coloring


Renovo do some quality soft top products including a re-colouring solution and re-proofer

once upon a time black boot polish was the recommendation, both for the fabric and strangely the window, but there are much better products for it now.
(works on the window because it fills the tiny scratches )

Get a Renovo kit. Will work wonders.

I actually think it might be cheaper to buy the above individually but it's what I've used in the past.
