How does the flatness compare to using conventional wet paper by hand? I'm assuming that if there is any urethane wave it should be gotten out by hand before switching to this type? What has always stopped me from using it is seeing what other guys work looks like when they use it. The clear/SS always has a wavy (not in the conventional sense) look to it. Wobbly would be a good way to describe it.
Or to ask my question a different way, if I'm using an interface pad and starting to cut a job with 4 or 5 coats on it, will it get it flat? Only way I would want to use the stuff is if I could get it as dead flat and straight as I can doing it by hand. Would be great if I could as it would save so much time.
