The car is leaking....
 

It's been raining a lot and I've discovered water spots on the back deck of my 1979 450SLC, near the rear speakers. Also in the trunk, around the perimeter. Anybody have this problem before? Change the backglass gaskets? Change the trunk gasket?

Also, I see a rust spot right where my sunroof opens up. How's it best to take care of this one?

Thanks in advance,
Ray

Rear glass gaskets often times leaked. I'd start there.
