I have a 3M clear bra on my 1996 BMW 318ti, red. I've had it for about ten years. It's not yellowing. In the past I used to hand polish and wax the clear bra along with my paint using 3M's Imperial Hand Glaze and One Grand wax — a common practice in its day. Three to four years have now passed with no detailing outside of regular washings. And now I'm using the
Ultimate Detailing Machine and
Ultima products. After practicing first on my wife's Jeep, I think I have the technique down to clay, clean, polish, and seal the paint. Now I need to work on my Bimmer. Should I clay, clean, polish, and seal the clear bra the same as my paint? In other words, should I use Ultima
Elastrofoam for claying, the
UDM for applying
UPPP, and seal the bra with
UPGP?
