If you love your VX, treat it to a nice rubbing of 3M Imperial Hand Glaze once ever 6 to 12 months a year. Your VX will purr for you.

Seriously, this stuff is what the pros use to bring luster to paint. I've used it religiously on all of the cars I've owned. Each sold looking as good as new. Follow up with a good coat of quality wax. Buy a bottle and try it on just one pannel and compare with the rest of your VX. The result will amaze you.
