Sorry for the shameless plug for Carter, but he does the sweetest machine work this side of Mars! Oh, Hi Carter!

If you want to stop the corrosion and retain the coolant flow you need to get rid of all the white powdery stuff. I used a brass brush + WD40 for most of it. Then I used acetone + paper towels. Then I used 1000 wet to make nice nice. Then, and I think this is the important part after removing all the white stuff & the pox marks. You have to coat the new gasket on all sides and the holes for the screws. Reason is to insulate the two metal parts and the screws from the coolant. It's electrolysis that causes the pox. Two dissimilar metals in contact with water ( coolant ) and in the presence of an electric current ( block is ground ). If you interrupt that circuit you're good to go. I did that to mine back in 05 when I did my injectors and it hasn't been back since!

Have a new plate coming from Carter. Coat the new gasket with what?
