good job. for my hobby cars i dont drive in the rain/snow so i only use Griot's SprayOn wax at best and just keep reapplying as needed these days. the surface so slick if you put a drop of water on the hood it will just roll right off with no residue.
As for clay i only spot clay once a year or once every 2yrs. i rarely get any comtaminants bond to the paint as i QD pretty much after each drive.
ive pretty much decided not to use any 'wax' or 'sealant' type products as it's over kill for my cars...and just use spray products (mainly Griot's SprayOn Wax, SpeedShine). for my dd's different story. i use polymers for them.
