Take it easy with the 0000 steel wool as it can take more off than what you realise before it is too late. Same goes for 1000, 1500 & 2000 grit when sanded wet, hence why I find 4000 & 6000 micro mesh more forgiving however it may take a bit of elbow grease before results start to appear. Better that than accidently sanding through the finish as has happened to me a few times.
