Corrosion Block
 

Anybody know anything about a spray called Corrosion Block? It's a commercial version of a Milspec item.

I'm wondering if it might be a good thing to spray on the case of a mag. tranny like a 911/01 type....?

I use it extensively on my boat an the aluminum Tower and I also take apart all of my electrical connectors (both boat and P-car) and spray them twice a year to prevent corrosion. I am a very satisfied customer and highly reccommend the product.

On boats we use sacrificial mg. to protect aluminum hulls and sacrificial zinc to protect steel. Mg cases are natural sacrificial metals.

Thx Bill - any thoughts on whether it would help a Mg tranny at all? I am out of $$ so will not pull it all apart and get it coated.
