Depending on the Modell - if it's one of the SK/LP/HP CBMs,
I recomend a ... ups, now I got problems since I don't know
exact american namings and brands - I would recomend ATA
(thats a brandname, but also used generic for most brands
of not aggressive Scheuerpulver (scpuring agent (?)) with
an aprobiate hard sponge (non metall), since the 'rough'
surface accepts microscratches, and the coulour used is
thick enough to allow this procedure - don't use any kind
of sandpaper.
For Metall case PET/CBMs with the rough surface the same
method might be usefull, but you have to prpare the Scheuer-
pulver with water in a seperate place, to avoide the first,
hard contact - also add some sadditional soup and use a soft
sponge with less pessure - you might need to polish it later
on with polish materials for cars.
For the smooth surface (early) models, I recomend only soap
and a sponge - and a real lot of rubbing. Also some helpers
as used for car paint refurbishing are usefull.
All this will only work to remove non aggressive markers.
If the markers have interacted deeply with the paint, and
or if spray paint is used, you have to do an repaint job.
take a medium to fine Schmirgelpapier and remove the unwanted
paint, until is is completly gone - try to take of material
all over at the same rate. if done well it might be enough
original paint still on the surface that you only need to
add a new gloss-paint layer - if not, considere to unpaint
whole case and give it to a car painting company for the
job to do it (including new paint of course.
The main problem is that you have to prepare all parts the
same way, since it would look terrible if only one side of
the pet is 'redone'
