If you do use adhesive tape on a textured panel, I would try to smooth out the taped area surface with a sanding disc, very carefully. Assuming this is a permanent setup you can grind off the top texture of the plastic for a better bond.

If you’re using 3M double face tape (3257) you can IPA wipe or pre-prime with primer (check the 3M website).

Clean the surface thoroughly to remove any oil or residue for the best bonding, no matter what you decide to use.
