glassing a dash

When glassing a dash how many layers should I do?  I am not going to add anything to the dash I just want it to look good and paint it.  I know to sand it first and drill some tiny holes in it to allow bonding but, how many layers should I go and should I use like 3/4 mat?

Thanks

why not just paint on top of the dash without using any glass if you dont want to modify it? what kind of car is it?

Well that sounds like what I will do.  Just sand her down prime her up and sand it again and paint it.  thanks guys.

clean the vinyl with a wax and grease remover first

rough the vinyl with like 220 320 i dunno something like that

clean again

shoot with bulldog 2-3 light coats

shoot a couple of layers of a 2k (prefferably high build) primer (DO NOT FORGET TO USE FLEX ADDITIVE)

spray a guide coat (black primer / or whatever)

use a soft sanding sponge w/ 600 grit and water sand smooth no guide coat left

base coat ( DO NOT USE A BASECOAT THAT USES A "HARDENER") until primer is fully covered probably 2-3 coats depending on color and color of primer

clear coat (DO NOT FORGET TO USE FLEX ADDITIVE)
