Ok, thanks for the info. I had this idea that I could use ferrex on a band saw top that had light rust on it and then use the opti-seal over it. I can say the Ferrex worked like a charm last night. Still have a few areas to work on. My Waterloo has been that the so called "rust inhibitors" I have used last maybe a week; sometimes only a day as the humidity has been very high
Again, thanks for the info..
