Ehhh, I wouldn't spray copper on the GM MLS, they are more than fine how they are. Now if they were Cometics, then I would lightly spray them to make absolutely sure they had a good seal to avert chasing down coolant leaking problems like some people have reported. I had Cometics and used copper spray on them upon first application and they sealed like a charm.
