I'd say no to the contact cement, at least where I live (it gets hot). I
have done this job a number of times, spending at times crazy amounts on
"professional" adhesives from upholstery places. It all came down
eventually. What worked best for me, hands down, was professional vinyl
wallpaper paste. It does not respond to heat or cold, dries flat (it sucks
the covering down to the substrate as it dries) and is never exposed to
enough moisture to undo it.

A second best is yellow wood glue but it is very difficult to use on
fabrics without looking like you used yellow wood glue. It's fine for
vinyl. It will not come down, ever, even if you want it to. You will end up
recovering the panel or making a new one.

When an area peels back as it did on mine where a rear window was once
leaking, I got under the edge of the panel and the peeled up covering with
superglue. I wrapped that in a plastic bag folded over the edge and left
flat clamps on it overnight. Problem solved. This was for just a six inch
area by say a quarter inch.
