So, I went through an automatic car was the other day just to get the summer bugs off my truck. The shade on the twin panel moon roof was open, and I noticed a bit of a leak between the two panels when the high pressure rinse went by. I've been reading, and some people will say this is normal, other people will say it's not. Does anyone know whether or not it's expected behavior? This is the first vehicle I've had with a twin panel roof, so I'm not sure.
