Hard to imagine that a car which is washed and waxed regularly would develop such a problem - to the degree you state.

If doing a near-factory quality repaint be prepared to fork out the far side of $5k, maybe more. Given Boxster resale prices, that'd be a HARD choice to make because you won't increase/maintain it's value by that amount.

But, that may not be necessary. The car could be color sanded (wet sanded through the etching), leveled and then shot with clearcoat. Figure $1500-$3000 + whatever accident damage from the scrape. This estimate can range WILDLY by region, so have 2 shops give you bids - if they're waaay apart, seek a third. Sounds like a bit of legwork, but you've stated you want perfection - that's the best guarantee of getting it.

You just cannot achieve a factory paintjob anywhere near under $10k, but with the color coat intact, a good clearcoat job will come very close. It's when you redo the color coat that you start seeing the quality degrade.

Make sure that the shop knows what they're doing, that they have experience with good clearcoating. Be sure to inspect the shop - their work will often reflect the shop condition. Make sure they have a good shooting/drying booth. Try the local Porsche Club or newsletter for recommendations.

If you're skeptical, have them color sand and clear one panel like the bumper cover. If satisfied, give them the rest of the car.

Cheers!
