Explorer,
Try Finesse-It II. I've had good results using this product by hand. Use a foam applicator, a small amount of product & really work it in with medium pressure at first and as the product starts to clear up, ease up on the pressure and keep working it in. Work in small sections at a time (1' x 1') It will still take 2 or 3 applications, but it'll do a good job with light to medium swirls. It takes me an hour or so to do one panel.
Follow this application up with a paint cleanser or your SMR (light pressure) if there is any hazing left-over.
3M SMR all by itself by hand didn't do squat for me either.
