Driving ZR 1 in wet weather

[kengodfrey]

I have a 1991 ZR1. After driving it in wet weather,it creates a loud, screeching noise when it starts drying out. Took it to a knowleadgable Corvette mechanic. He told me to continue driving it, the noise would go away. He was right, but what causes the noise? Really embarrasing with all the noise.
