Prima Banana Gloss is great for when you're pressed for time or when you're dealing with moderately imperfect paint. To elaborate on what Pats300zx posted above it is very quick and forgiving in application, nearly impossible to screw up. It fills a bit, almost as much as some products sold as glazes, so it will hide minor paint flaws but this also means it will mute flake to a degree. I do find that it tends to attract, or at least hold, dust and pollen. I get a lifespan of a month or two out of it, at that point I'd want to clean it off and reapply but YMMV.
