If you are talking about
08P42-TGS-100B Seat back protectors then I do not believe so.
The instruction tell you to insert the snaps into the mounting holes and then put tape over them to hold them in place. The making tape on the back of the seat in the area of the mounting holes is to provide you with a way to see where the holes are to be drilled. The making tape is removed from the seat back after each hole has been drilled.
If you are not feeling confident in mounting the seat back protectors you might want to refer to this at the top of the instructions.

Velcro does not have near the holding power, plus stick on velcro peels easily in the heat, and we all know that vehicles get hot in when parked outside in the summer, especially in the sun. You could try it, but don't throw the instructions and parts away, I suspect you will need them.
