D.I.Y Dash Cluster refinish

It was recommended to me to use SEM black trim paint for repairing my 70 Duster rallye dash. It is supposed to pretty accurate to the original dash color. I ordered mine from Eastwood only to find out that the local Carquest carries it. It can be used on properly prepped metal parts without a primer. Part# 39143.
How did you prep yours ? The dash panel is plastic .
I also have a console to do . I took the inserts out of the console and used paint stripper to remove the 3 layers of crappy paint someone put on it over the years . There is some light pitting to deal with .
Thanks
