Some the material was dropping on my parcel/hatch and I decided to recover it in black suede. The material is a synthetic suede I bought at a local hobby store. It has a white foam backing. I wanted to find it with black foam, but I had no luck.
I removed the shelf from the car and removed the plastic hardware and tore the material off both sides. JLR uses poor quality adhesive on their cars. So, this is a common issue especially if you live in a warm climate.

Heres what it looks like with the old material removed. There is a hardened foam mess left that has to be removed.

Next place it on a table outside because this crap gets everywhere. I used a wire brush hooked up to an electrical drill. The battery powered drill didn't spin the brush fast enough.

Heres what one side looks like with all the old foam removed.

Next is the tough part. I used a quality spray adhesive. The trick is to spray the right amount of glue. If you spray too little of it will end up sagging in places in the future. You spray too much of it will soak through the suede. Once the suede is glued down work the material in all the crevices with your fingers. I was surprised how well the material conformed to the round surfaces.

Next use a small scissors and trim around the edges.

The problem using a white foam backed suede is that the edges are now showing. I bought some U shaped rubber channel and used it to the hide the edges. The rubber would not contour around the tight bends.

I'm not super happy the way it turned out. if anyone has ideas on how to hide the white edges please post. Maybe a suede with no foam backing would have looked better..but I couldn't find it.

 

My first thought was black paint -- acrylic paint shouldn't react with the foam, although you'd want to test on some of your scrap first. The downside of just painting is it wont protect the edges from wear and unraveling.

Maybe some double fold bias tape? This is normally sewn on, so I'm not sure how you'd secure it with the fabric already attached to the board.

 

I would try coloring the edges.
the fusion for plastic has tremendous hiding ability with one quick coat. It also dries rather quickly, since you don't need to 'wet' the surface with this colorant whatever solvents are present would I dare say, barley affect the foam.
I'd buy that in black and give it a squirt.
The Duplicolor vinyl and fabric might also be an option, it's solvent base is qa bit stronger though.
