I have a bit of an issue with the head-lining in my car and it needs to be completely replaced
I have an idea of how I would replace it, but it is probably wrong and will look, well, cack
I know where to buy the material from, and have most of the foam from under the old lining, although it is broken and cracked/torn in places.
What sort of prep work do I need to do to the foam?
Also, what glue should I use and what is the best process to get a good finish?
