Fantastic Trim Protector
Just used this on the interior of my S3. Results have been excellent. The finish is Matte (obviously) but with just the very slightest hint of satin - basically a factory finish. Where it excels is on the flat plastics, so on an S3 these are the centre consul and the trim on the seat backs and around the hand holds on the door cards. Better than new. Use exactly as directed and take the time to use an applicator sponge or pad rather than spraying on a microfiber towel. Buff off excess immediately with clean polishing towel. Over spray comes off with glass cleaner on polished plastics and window glass. Not difficult but worth the effort to get it right. Couldn't be happier with the results.
