I'd be interested in the result.
I saw this thread the other week.

Being as I'm a complete cheapskate, I thought I'd give the dishwasher rinse aid trick a try first.
Developing the idea a bit, I used a Miracle Grow feeder (£6.99 from Homebase) attachment for a hose pipe instead of a watering can. Dilute a squirt of rinse aid with water in the feeder reservoir (see pic below) and rinse the car with this solution after washing. The feeder allows you to switch between using just water or the diluted rinse aid, so you can choose when you want to use it.
My Saab was the guinea pig for this and the results where superb. No water marks using Anglian Water 2008 vintage rock hard water on a black car! After a quick dry with a combination of a silicon blade and a micro fibre towel here's what it looked like:

File comment: The car got rained on overnight and the rainwater has beaded just like when it's been waxed.

This is the Miracle Grow feeder. Maybe if I put some Miracle Grow in it and use it on the Boxster, it might just grow into a 911.
