It's easy to do. I did mine several years ago using grey leather. Here is the major problem.

The base "board" is not solid. It's more like a loofa sponge. It's like it's woven with gaps in it. Google what a loofa sponge looks like if you have to.

So I used contact cement on both materials and gave it time to dry and for a few months all was good. But in some areas that had depressions like above the sun visors, it drooped.

I think what kept the old cloth to adhere to all the contours was it had foam between the base board and the cloth. You must remove the old foam before proceeding. I used a very fine wire wheel in my drill.

You might want to google ways to deal with the "gappy" base board. call around to different upholstery shops. Maybe consider putting a good quality very thin closed cell foam on before your final material.

If I had it to do over, I would have put a thin closed cell foam first and then my leather. The foam has to be thin to adhere and show the contours well.

Good luck to you.
