It's a bit messy, and the instructions are not really clear, but I eventually figured out how to get the lid off, though there was a little bit of splatter when I did so. It is best to wear old work clothes when you use this stuff. Initially, it was surprisingly runny, but it tried quickly. So I took about 15 mins to carefully use the little brush to coat over the places that were rusting as you can see in the first photo. I let it dry for an hour, then used a pad attached to my drill to buff it. I have not put on the clear coat (which did leak out of the bottle some). Not sure I'm going to. I'm certainly no professional at this, but to the casual observer, they will no longer notice the rust spots. For what I wanted it works. Better instructions and a better container would be nice, but it worked.
