Fabric painting

I have a 1995 VW autosleeper trooper. The internal wall and roof fabric is a little tired and faded but in otherwise good condition. I was considering going over it with new fabric, however I recently saw some Fabricoat paint and wondered whether this would work instead. Has anyone else tried this?

Thanks, Paul. I've just posted a 'hello' over now.

I've contacted a few people and it seems it would be fine. I'll try it on a test patch and see how it goes. I'll report back with some photos of the result!
