Another $4 well spent: Vinylex plastic/vinyl napkins. They clean really well and not too glossy. Requires some buffing after used for best look. I used microfiber to buff. It might be a bit on the glossy side for like 2-5 days, but it's just perfect after. I'll let pictures do the justice. Doors were done a few minutes ago, dash- 3 days ago.
