If it's been a few years since the car has had a polish, etc. I'd recommend this stuff. Dead easy to use, spray on, leave it a minute or so and then rinse off. It'll remove a lot of built up crap in the paintwork. I think it really helped bring out the shine in my friends car.
Once wash, use this stuff. Then clay bar or liquid clay if you are lazy like me.
Polish, hand polish and do use one of those circular sponge things, helps you get an even pressure and even spread.
Bilt Hamber also do a post polish spray to clear residue.
Now your wax.
You can go crazy with these things with an infinite variety of products, @toadster - your car is looking mighty fine, but, if you feel you've built up swirls etc, then a good polish is in order
