Hi,
I want to detail the trunk on my Retractable and replace the mats and boards.
I have had the car for 12 years and the previous owner put some type of adhesive down to keep the burtex mats from moving around.

Any recommendations on what to use to get the glue etc off the paint. Im not sure if they used a 3m type spray or something else.

Also when I replace the mats should I glue them down or just put in place and leave as.

Thanks
