2002 back when I 1st bought my WS6 'Firehawk' SLP Perf. TransAm GT
it was black, I wanted to save the OE paint
not do (dry wash associated) swirls or (dry wash stuff) scratches in if I could
I tried a bunch of them
the car never seen rain or snow ever, I was down in Rancho Murieta Sac. Co. still
lots of construction of new home on the 'south side' (mostly younger crowd)
of Murieta back then
it was really growing, it was like the final last phase of the buildout...
It got dusty even sitting in the garage, if I left the garage door open for any time
to work on one of my classics or 4x4s
Meguires, Ultimate Waterless, back then was the best
(used the same stuff on my racecars between rounds)
tried a few others, were way worse, cheap junk, not worth it
even then still got the
dreaded dry wash swirls
especially see them on the hood & behind the T-tops roof sides, of the paint
& the wings maybe because of a different paint used on the fiber reinforced plastics
FRP used to build the bumper covers, wing & spoilers, it's flexible paint was really soft
most would buff out with the wax/polishes, but if you've ever owned
a Onyx/Black clearcoat pearl car
had like a pearl in the clearcoat too, it really showed swirls
you know how quick they can get dirty, look like sh*t
I switched back to using water just not soaking the car,
& a Meguires heated blower, great PSI of air too (a gift from my nephew)
to get any water left out of the cracks, I used water sparingly too
another all in 1 wash & wax product by Meguires too...
after;
I did the last polish/buff after the waterless fiasco,
waste of time & $$$
it sparkled, she gleamed like crazy, reflections like a mirror, with absolutely no swirls
not much water left ever either, or minimal if any
Dry wash stuff, it may be better today (?), but I think it's a risk to a paint job
all that dry rub/wiping down stuff
I used a Meguire detailer 'spritz spay' in between washes, like 2 times a year,
a California Duster, kept it clean, the dust off
never had the swirls again after, even with the duster use
different folk, may have different results
that's mine
old school still works,
& I just use of water sparingly,
all I know use 'new mirco fiber cloths (no sponges, that hold grit)
& a clean real deer hide Shammie
this was what it was on the showroom
it looked even better after I owned it
my RR has been painted OE style acrylic lacquer base clearcoat LL1 Surf Turquoise Poly,
(garage paint job), since Nov 2017, all I do is dust it off, it hasn't seen any water yet
I have used water on the wheels & tires or underside of the car
after I went down a gravel road, up here...
California Duster works great
each of my vehicles has their own dedicated duster too
it gets dusty, but never driven in rain or snow
the B_I_T_C_H is pampered, never really left out side
unless driven, so is my 1999 Dakota SLT 4x4, same treatment
these Dakota/Dodges were suspect to show clear fading, flaking,
dark emerald green pearl & sliver
especially on the roof & hood when exposed to harsh sun or cold weather
& after 25+ years, my process & taking care of it, driven in all condition
& I have none still...
It stays in the garage when not used too, but lived outside
in Rancho Murieta for a couple years, 'seemed to weather it well'
when I had too many drivers & too many cars for my garage
no rust no swirls really, except for using a sponge at one time
I have since quit using the sponges, need to do a good polish again
Results may vary
