How do I fix streaky Krylon High Heat paint on brass fireplace detail?

Question

I attempted to paint my brass fireplace detail with Krylon High Heat paint. It’s 3 sided with doors that have a brass strip on the top and bottom. A couple sections ended up streaky. Can I sand it and repaint it? Can I sand it and spray paint it? How do I fix it? It seems like an oil based paint instead of the latex paint I’m used to working with.
