I am thinking about doing a few little things in the interior in pearl. I bought some of that cheap stuff from wally world. The interior is the light grey. After sanding it all smooth would I need to spray a base white? Also the front windows are tinted 5% and the rest are the dark factory tint. Would the pearl show up well enough to make all the work worth it? I think I might do a small part and if it looks good I have a few friends that work at body shops. Any opinions or advive?
