I have an older galvanized honey tank that I acquired (for free) about 5 years ago. It holds roughly 275 gallons. I don't think the inside of it had ever been coated with anything, so I got some of the plastic coating from Kelley (catalog # 353) and coated the inside of it. Over the last few years the coating has been peeling off while cleaning it out with hot water. Not sure now if:
1. It is worth the effort to re-coat it? And do I try to scrape/clean off the remaining coating?
2. What to use if I do re-coat it? Anything available that is more durable?
