I went to one of those charity type car washes once (in my vette) for a group that was trying to raise money for whatever it was at that time. I let them wash it (in the sun) and the hood,roof and deck lid turned a oxidized rainbowish look.

They said that they would pay to fix it but I told them not to worry about it. It took me hours to rub it out and wax it back to a normal finish.

Now that could have been from a crappy paint job or from the fiberglass gassing, I don't know. That is when I found out about letting them set in the shade and that it is best to wash them around sunset. It gives you time to dry them without as many problems. Really this is best for any car, not just fiberglass ones.

Of course this was in the 80's so a lot of things probably have changed by now with paint and such.
