automated

Ok, I have this automated pressurized car washer in my neighborhood (water only, no brushes). I'm trying to decide wether to take my car throught it for its FIRST was. The only reason i'm considering this is cause the pipe for my hose is cracked. Will this wash damage the paint in any...

Whats your guys' take on these things? Are they ok for your car. We have a couple in town that only use high pressure water to clean your car. People say they are great. But I've heard that high pressure water actually "force" the dirt into your paint. Only $5 and no use of brushes.
