I had the opportunity to work on a coworkers '03 trailblazer that was SERIOUSLY swirled. I worked my magic on it with megquires swirl remover (#9) x2 and a green pad, but was seriously depressed on how HARD their paint is. I knew the older models were tough to fix paint blemishes, but dayum not an '03. Scott can you give some products that would help out the next time I run across a stubborn gm? Also, it seems as though most of my buisness is dark colored cars (green, black, blue) and good combo's for specifically dark colors?
