Now 9 months and 2300 miles later I will give you an update on the "face lift" of the brake calipers (with a p). They look exactly as they did the day I painted them. Though this is NOT a job for everyone. It takes time and a ton of patience. A lot of sanding and cleaning. A lot of masking off and 4 light coats of yellow (drying in between) Porsche decal carefully seated and then 3 light coats of clear paint. All in all 7 hours of work per wheel. (I can see why a shop would not do it this way). It would be way too labor intensive. I did take her in for a complete flush after.
My surprise was the lack of brake dust settling on the calibers compared to before. Could be the new STOPTECH pads I installed as well.
YES......it can be done!!!
Picture is from today before I even dusted them off.

UPDATE:.
