I want to paint an f-hole on one of my guitars but im doubting between my ibz rga 32 mol and my yamaha pacifica. now since this is a first for me can anyone help me out here? im thinking it would be easier on my ibz cause its an oiled mahogany finish and thus means i wont have to refinish the entire guitar. or am i mistaken? can anyone provide me with a good starting point or strategy on getting this job done OK?

Many thanks guys

How about actually recessing an f-hole? Cut a template from MDF and use that to route the f-hole on your guitar, even if it's only a few millimetre. You could then paint or stain the recess black.
I saw some f-hole decals on e-bay. Maybe that would be a faster, cheaper, way to try. Good luck.
