Maple is beautiful wood but , it is also pretty hard and dense (I'm sure you folks know this

) , thus it isnt going to absorb that much sealer , tung oil , etc.
I have gotten nice results with woods as hard as Desert Ironwood by doing the following pretty easy steps.. Sand to 1500 or finer if you can find it , you'll see a "gloss" just from that fine of sanding , clean with de-natured alcohol after completed sanding and let it dry , a few minutes.
The initial coat of tung oil , I would make light-to medium thickness , at this point it will absorb about as much as it's going to absorb , let dry for a few minutes and then buff off witha lint free towel , hold your project in the light so you can see any lints or gummy's as sometimes tung oil will gum up in spots during that buff.
Let that dry , maybe a day if youhave the time , then repeat the process until you get the desired gloss, using lighter coats of tung oil or course.
Now this is how I do it but I do all of mine by hand , no buffer or whatever.
Like I said the resulting gloss on the desert ironwood scales was beautiful and shiny with the added benefit of further waterproofing , without looking like it even had a finish on it.
Good luck bro.
