I recently refretted my old defretted Aria haha
it was a bit of a task simply because the guy who defretted it cut the fret slots a little wider to fit the wood veneer in! i managed to saw the veneer out quite well, trouble is the frets were way too narrow for the slots! so after filling and recutting the slots i managed to do a pretty dam good job considering its condition and the fact it was my first ever fret job! turn out to be quite playable so im very happy with it!
All i'll say is buy the right tools for the job (if you dont already have them of course) it makes things way, way easier
