I use sem stuff for all my interior stuff. I've repainted my dash probably four times already, plus a pillars, console, and kick panels. I've got the color code downstairs, if you have the tan interior.
I'm workin on the new version of the cardomain page. You can check out my old one at www.cardomain.com/id/lashlee . Once I get the new one up and running, I'll post it there!!!
I start with cutting a hole, glue the tweeter cup in place, stretch grill cloth over it, then use resin to harden it. A coat of body filler, and paint!!! It's one of the easier ways to make most setups sound better!!!
