Two points to weigh in on IMO:
- Are you talking about a “usual” satin or flat black refinishing or a gloss black refinishing ? I would not try the latter requiring multi-coat applications, sanding, and fine polishing as a DIY project.
- Without prejudice to the above, a bespoke non-OEM new radical refinishing color ; ( and especially in a DIY effort even with your advanced woodworking skills) will kill its successor owner appeal pool , and especially kill its FMV resale value should you wish to ever sell them later,
