Having invested time and money in an exotic car does not make rust any less nightmarish to say the least. Rust is inevitable.
Nature eventually reclaims everything.
The thing to remember about rust on a car is that serious rust starts on the inside. Don't worry too much about paint chips. Chips don't look good, but the surface rust that develops there often never amounts to much because it's usually dry. The nasty stuff grows on the bottoms of your doors, in the rocker panels, wheel wells, under windshield gaskets, etc. By the time most owners see that kind of rust, serious, expensive damage has already been done.
