I guess I'm lazy.. I'd rather be driving. I use the local spray car booth a lot. $5-$6 gives me plenty of time. I spend more time with my brakes and under the car than the rest. Huge amounts of brake dust. The salt is embedded in the roads, and a few miles on dirt roads.
Then Krown 2x a year. It may not look the "best", but it will last and I put the $ and time into maintenance and parts. It still looks pretty darn good though. I may pay to have it detailed and ceramic coated.
The "Wax on Wax off" exercise is not on the agenda for my old body. Last time my back went out for 2 wks. Ugg.
