Ive used clay a couple of times one thing for certain you will not be disappointed its incredibly easy to do and amazing results
Of course theres a myriad of products on the market but which ever brand you chose the order in which they are deployed should remain constant
its important to distinguish between polish and wax
wash -> clay bar -> polish -> wax
I use a combination of Autoglym and Meguiars
wash -> Meguiars NXT Car Wash (purple)
clay bar -> Autoglym clay, lubricant either Autoglym Rapid Detailer or just a soapy solution as above
polish -> Autoglym Super Resin Polish
wax -> Meguiars Deep Crystal System Step 3 Carnauba Wax
good guide on how to clay
