Well, after reading many posts about removing frets, I have decided to convert my old MIM Jazz into a fretless. However, there is one step in the process I am wondering about: applying the wood filler. Should I use the coarse sand paper before or after applying the filler? In Dancehallclasher's recent post, he mentions that he did the coarse sanding after applying the wood filler. However, in other threads and sites, the coarse sanding is done before applying the filler. IMO, I think the idea of coarse sanding after applying the wood filler is the better option. Any opinions?
