Water Pump Corrosion

Help an old duffer with a bad memory. I thought I had read in MXA of a preparation used in drag racing that you could spray onto magnesium cases to make them imporous and less likely to corrode around the water pump. Any of you guys with older CRs remember this or have advice?

The cover on my 86 was so bad that it was destroyed.

FWIW...

http://www.devcon.com/. These folks do products that repair corrosion after it has occurred and then make a protective barrier.

http://www.evanscooling.com/. These folks do water-less coolants that claim to prevent electrolytic corrosion in magnesium-based engines.
