1. I have found that applying Back to Black on the dull aged OUTSIDE black plastic trim with a sponge is the temp solution - good for, until after 2 or 3 rain storms.
BUT DO NOT RUB IT IN OR BUFF IT! JUST WALK AWAY! Takes 5 minutes.
2. Use a damp MICROFIBER cloth to wipe the inside windshield.
3. I lowered my too high cold fast idle AND too high regular idle by turning
in the BISS screw on top. I grounded NOTHING. Idle is still where it should be.
I turned the screw 1 revolution at a time with the engine off & put back the black rubber plug, before restarting. Mine required two 360 degree clockwise turns of the screw.
