LOL ........ guess I'm following Jopa around here.
I agree with many of the products Jopa listed. As mentioned the CG Citrus Wash is a greta car wash shampoo.
I also have found the Dodo Juice "Born to be Mild" to be GREAT for the maintenance washes. This stuff is made to clean without removing previously layered coats of wax from the paint. A maintenance shampoo really.
As far as a sealant ..... Jetseal 109 is pretty good and I've used a bottle or two. I prefer to use the Menzerna FMJ sealant more often though. It seems to give a deeper gloss much like a wax with the ultra slick feeling. It is undoubtedly the easiest product to apply and remove I have ever used.
As for a leather cleaner I recently began using Poorboys World "Leather Stuff". Cleans/conditions without the greasey look and leaves your car smelling like new leather.
Everything else mentioned in the post above is pretty much what I use in my own car. Have at it and enjoy the results!
