Works ok it give a deep black rich color. I did it first by hand, then a few weeks later with my Portacable 7424 XP. It does not remove surface searches that well. You must also wear gloves or you hands will be in black condition.
The key is step #1 once you are happy with the surface then go to step #2.
Has anyone tried Adams Swirl remover with the 7424XP?
