Anyone familiar with a product called Ospho? It is a chemical to retard and nuetralize rust. Someone suggested it to me with respect to my problem with the steel ballast in my keel being wet. It is drying out, but now that air is in there it is obviously going to rust. The suggestion was to inject the Ospho into the area and let it coat the steel punchings. Ospho apparently has about the consistency of water as far as how it flows. This sounds like a do-able idea except I have no-idea what the effect (if any) on the fiberglass would be. Honestly, unles someone tells me that they have seen this done, I'd probably shy away from it. So far I haven't been able to get in touch with the company that makes it to ask them how the product would react with the glass. I'll have to try earlier in the day on Friday when I'm off.
