Green car: reverting to AIO + SG X2 with fortification provided by Sonus Acrylic Glanz as needed.
utility car: repeat AIO followed by Collinite's IW ! (What a look! Thanks, Spilchy!)
Silver car: not driven in inclement weather, just re-done with Paste Glaz this past weekend, probably nothing else this year.
Blue car: perhaps one more session with WPS.
