I use near enough everything!!! lol.......
If you just want a basic stuff i'd go for their tech wax car shampoo, tech wax, glass cleaner and tyre shine gel.
Ive got all the extra's like the gold class clay, strach-x remover, metal polish.........the list goes on!! Got a nice meguiars bag to carry it all in too from one of the competions i won! =]
You can get it from all good car shops, halfords or even from meguiars website!!! They arent cheap but the results speak for themselves!
