There is absouletly nothing to worry about!
I have gone through those touchless car washes about 5 times since i owned my car. I haven't even washed the car myself yet! (lol) NEVER have i had problems. The high pressure wash is REALLY high pressure as i can feel it hit against the car, but hey, that's the only way the dirt will come off!
Overall, it does a decent job. I'd rate those touch less car wash 8.5/10. Soft cloth works better IMO, as they actually touch the car to 'wipe' the dirt off. But i don't feel comfortable going through one at the moment. Ever look closy at those cloth? they are soo dirty!
2 coats of soap? No way!, i only see my car get one application.
Those dryer at the end of the car wash is soo powerful! I think they blow at over 200km/h wind.
nothig to worry about accept maybe for the 17" Racingharts that are in the roller that pull your car in. I'm currently on steelies with 65 series tires, so i have nothing to worry about. I don't think i'll go into a touchless car wash when i have the RH's on this early spring.
If i worked at those touch free automatic car wash, i'd drive my car in there EVERYDAY!
Btw, can you do that since you work there? I mean, do you get free washes? I just got my car washed today through a touchless wash.
