Question about care of old exterior paint
« on: October 24, 2010, 05:37:46 AM »

I fear I'm damaging the paint on my car every time I dry it off.  I've got a '79 Mopar vintage paint job (enameled paint, not clearcoat) and, over all, it's in good shape considering its age.  However, in some spots, it's a bit thin from age, wear, etc. so I'm worried about its longevity as I do NOT have the resources to do a proper repaint anytime soon.

When I'm done washing the car, I use a regular, synthetic (feels very rubbery when wet) chamois / shammy / whatever they're called - to wipe away the water so as to not get spots.

But each time the chamois is full and I wring it out and watch the water as it comes out of the shammy, I notice the water is the hue of the paint.  I'm, in essence, rubbing the paint off the car when I dry it.

So how am I supposed to dry my car and not thin the paint at the same time?  Are there "frictionless" shammys/chamois?

Probably not, wherever any friction is involved on bare paint some
removal, however miniscule, will occur... you could always go to a
brushless car wash that uses forced air for drying,  but if you
wax it well with 100% Carnuba wax (no cleaner) frequently, you likely
won't remove any significant amount of paint during a normal wash/dry
procedure. Don't use a power buffer though.

The white coming out of the chamois when wringing it is probably oxidation more than the paint.
Like Roger said,use a good wax to remove the oxidation and protect the paint.
FWIW,I use real chamois not the fake ones.Personal preference,but on old enamels and laquers I find they work better.

I've never used carnuba, but I'll look into it.  What do you mean by "no cleaner"?  Do you mean to only wax the car, not wash it?  Or do you mean if I wash Wanda, then wax it enough, there'll be a "build-up" of wax so the friction from the chamois will remove the wax and not the paint.

No power buffer?  Oy....Wanda's a big girl to wax by HAND.

A "real" shammy......What's so special about real ones?  Are they made from unicorn leather / do they grant wishes?

Some waxes have diatomaceous earth powders in them that clean,
essentially, by polishing off a small amout of the paint; you don't
want those. 100% Caranuba (a Brazilian nut) wax will not take off any
significant amount of paint, but will put on enough of a protective
coat that, if it appliled a few times a year, will protect what paint
you have left.

PS:  a Chamois is an African (I think) relative of the Impala or
Gazelle and their skin is used for removing water from cars  by
wiping, due to it's highly absorbtive properties. Old school but it
works.
