It’s coming along nicely but very VERY slowly. However this is of my own doing as I’d rather take my time and know that I couldn’t do any better.
Firstly the whole of my roof lining was sagging.
I then took a stiff brush to the foam that remained on the board and Alcantara. This is a messy job and best completed in small areas at a time. Remember this foam is sticky and you don’t want to get it on the Alcantara as it’ll be a bitch to get off.
Like I said this is a long job. You need to keep cleaning until you hit that wall and want to stop. Keep cleaning! This kind of job is all in the prep. By now your thinking that will do. KEEP CLEANING. You need all the spots of old foam gone or it may show through as lumps when you stick it back do. Now you’re think about burning the car and it’s only a roof lining, who the hell looks at the lining anyway!
KEEP CLEANING This is going to look great when you’re done! Now you’re thinking the wife might be right and you should just sell the <beep> car!
You can stop now. 
What’s left behind should be a slightly tacky surface but effectively spotless.
Now I wanted to keep the same plush finish as standard and by gluing the Alcantara direct to the board wasn’t going to achieve this. I visited hobby craft to see what they had but couldn’t find anything appropriate. I then thought to visit a local carpet
Shop. They had some 10mm underlining, this is significantly thicker than the original foam (at around 3mm) but I thought I’d give it a go.
Using some no nonsense liquid glue I’ve stuck the lining to the face only and will trim when the glue sets.

That’s as far as I’ve got.
