i wiped down my MCS interior as well... then masked off areas that I
didn't want dressing.
From my experiment, I think the best way to apply vinyl & rubber
dressing is:
1st, put maybe 2-3 small squirts onto the blue Griots's sponge
(very little).
2nd, start from the bottom of the door panel (bottom meaning facing the
ground, not the lower part of the panel facing you) apply the dressing
while you work the dressing evenly onto the sponge.
3rd, work the dressing from the bottom of the door upwards to the
door jam side, then to the front of the door facing you. keep going
up and finish at the top of the door. by that time, the dressing is
very evenly dispersed into the sponge and very little is left in it so
you can't over do it.
Too many times i see people start from the top of the door
resulting in an unnatural shine at the top.
repeat as necessary until you get the right amount of dressing on
the door... again, don't use too much. you might want to just
keep rubbing the sponge with no more squirts of dressing. just
work it in over and over again.
The Griot's dressing doesn't shine much which is a good thing.
If you ever decide to buy their dressing, just get the small 8oz.
You will need no more than 10 squirts to do the entire car.
If you're scared to do the dressing on the interior, try their SpeedShine.
I did that before to clean the door panel and it turned out real clean
with a nice matt finish.
