high-pressure wash should NOT take off your paint! shitty paint will come off in a stiff breeze. my own car was resprayed by a moron (not me!) paint flakes off with a garden hose (you can see why i never wash my car!) original sahara color is still there, often (one can tell) still its original glossy finish under the newly blown-off respray chamonix. In other words, the idiot didnt even bother to degloss the sahara in certain areas.......

First of all you got 9 years out of the respray and also you kept your 02 for that long, congratulations on both counts. UV rays will attack the clear and degrade it, just like anything else paint has a lifetime, it doesn't last forever. Damage can be mitigated by care, and mostly by keeping the car out of the elements. Usually it is the top surfaces that show damage first. You may be able to get away by respraying those only. It is common practice to sand all the clear and then base coat and clear coat again (kind of difficult not to mess up the base coat during sanding)

Just as an illustration: I recently saw a 96 Z3 whose original clear was basically all gone! Our 97 (sold since) was a garage queen and its paint look flawless.

color sanding through the clear and polishing the color may look pretty good, or maybe not good at all. Amazing results can come from colorsanding a very faded old paint job but would it work on a clearcoated paint job?

Moral of the story:

Clearcoating sucks.

99% likely that it's basecoat/clearcoat....the base coat can't be color sanded, it's not meant to shine. base is a dull coat that only provides color....the clear is what shines, gets buffed and or polished

no quick fix

the new (last 10-15 years or so) systems

actually chemically bond each layer toghether,

and specifically call out MAXIMUM times between coats.

If you wait longer, the solvents in the next layer won't be able to bond to the layer beneath, and the paint will come apart.

So, for example, sanding between each layer of clear would cause delamination, since the 2-3 passes are supposed to chemically bond.

Now, having said that, if you choose your products correctly, (using a single stage paint as a base, usually) each STAGE can be allowed to harden, then sanded, then shot over.

You're right- that would be one sicko show car, maybe with layers of flake or pearl...
