Subscribed. I've used the old formula and really liked it. But havent used the new formula yet. I want to know the same thing, how does it do with gas. I havent given it much thought about a clear coat. Most I've read about use an automotive clear coat. I normally try to stay away from the real caustic kind of paints but I may not have a choice in this case. An alternative might be latex on the next project.
