Corrosion Block

[Randy Webb]

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.

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.
