I know its mostly a cosmetic issue, but i really would like to sort the head liner out. Its sagging in the rear load area, but more annoyingly the sunroof covering keeps falling on my head!
I've seen the kits from martrim, just wanting to make sure this is the right stuff:

I want the black fabric which isnt listed as a kit for the range rover, anyone care to suggests how much i need? I'll probably cover the A/B/C pillar trims as well if i can?

I think the kit gives 3.5m but if you ring Martrim and tell them you want black for a P38, they'll sell you the correct length. It's quite generous too, you'll have plenty enough left over for the pillars. Only problem with doing the B post trims is getting a neat finish around the sliding bit where the seat belt top mount comes through.

Main piece of advice is to make sure you have one, if not two, assistants when you come to do it. The Martrim glue is possibly the stickiest of sticky stuff on the planet.
