Okay, from the other threads i have gained i need to do 3-4 coats of SEM landau black on my interior.

my question is how many cans will it take to do my whole EK interior?
do i need a can of that prep stuff? how many?

can i get some instructions to take out my dash?

some people said they used something to scuff the dash/interior peices up, who didnt do it?
