Haven't actually got round to waxing our car yet, washing it seems to take enough time, especially getting rid of streaks.Used one of those Flash car wash things to clean it. The auto dry thing it does is quite good, didn't think it would work but will dry with no water marks. Then used TurtleWax Color Magic black wax.
The best way to get avoid streaks when you are drying your car, is to rinse your chamois after each body panel has been dried.
That's the strangest bit of advice I've come across on here !!Maybe the grass was polished with Green Turtle Wax Colour Magic. Have you tried pee-ing on your grass, well not directly, but bottle it and water it down, don't know the exact ratios, so you might want to read up on t'internet somewhere before running out to the garden in the night to pee.
Apparantly it works really well.
