I bought some wheelbore polish #2 last summer, used a little in the fall, and didn't have occasion to use it until earlier this month. I found that the polish had caked up quite a bit.

Is it still usable or is there a way to refresh it? If not, is there a suitable substitute, or do I need to buy the Red Rocket stuff?
