Depends on the polish, most are a one-step oxidisation removal and wax
giving the typical 'water bubble' effect. Meguiars do have a polish and an
optional liquid wax finishing coat, but unless your paint finish is liquid
smooth (mine isn't) the latter is a waste of time and money.
Red pigments suffer more from oxidisation than blue/green. However I would
never use an orbital polisher on red cellulose if that is what you have, it
is too soft. Even hand polishing gets a worrying amount of pigment onto the
cloth, although after 21 years there is only one tiny spot of undercoat
showing through, on one of the raised seams between wing and screen scuttle.
Polish type is also very variable, I've never used Meguiars but Turtle
original (white cream) removes quite a bit and gives a good gloss, Turtle
modern (clear liquid) removes hardly any but only gives a dull finish.
AutoGlym (white cream popular with concourse) is a good compromise between
the two. Mer didn't take any colour off, can't remember the finish as I
stopped using it many years ago as white streaks kept appearing in seams
etc. for weeks afterwards. The 'water bubble' effect can also be damaging
on soft pigments, leaving white blobs if you get a shower then strong
sunlight.
