I have a project Mexican Telecaster that I put new locking tuners on. This left exposed screw holes that I would like to fill and finish. I saved some chips to make matching filler or I might use the maple colored filler from Woodcraft. My question is what is the clear finish on this guitar ? I don't know whether it is a water based finish or laquer. I was thinking I could mask off this small area and carefully apply the finish with a rattle can or maybe it would be better to brush or pad it on ? Thanks for any advice.
