there was a recent thread on washing the car.... lost it though.
it went into the clay bar process.
Self-serve wash isn't bad. Just make sure you dry thoroughly after and don't just drive off. But you gotta wash fast (cuz they always cheat u on time for what u pay lol)
High-press soak, Foam brush, High pressure rinse, Light rinse.
If you're good, u can do it in about 5 minutes tops.
over here it's $2.50 for 8 minutes..... just fyi
