Right away! Best thing you can do is to start caring for it while it's new to keep it in mint condition. I used to use combination of different brands, really depends on preference. Now I use this stuff called Crystal-Glo Paint Treatment (you use it instead of a polish and wax). I bought it in a Sears store in Montreal a few years back while visiting for the F1. Now I just order it online www.crystal-glo.com or pick up a few bottles when I visit.
