Back in 1998 I bought my 1997 BMW Z-3..........the dealer told me I would never need to wax the car and that I should never use any abrasives (no matter how gentile) because of some finish he had done to the car.

He was an exotic cars car dealer....my BMW was the cheapest car on his lot, any way I really have neglected the paint on this car......hardly ever needs washing, never waxed it.......I've left it outside most of the time summers ans winters.....it still looks fantastic, like a very high end custom paint job......never water spots....

My question is............what the H*LL did he do to it?????

I'm telling you I truly abused the paint on this car....drove winters on salted roads.....grandkids were always rubbing their dirty hands up and down the sides.......nothing seems to hurt it!!!

He moved away and closed shop many years ago so I can not ask him.

I'd love to be able to do the same to my BLACK 05 COUPE
