I did a superglue finish on a knackered old Warwick I defretted. It was pretty easy, just time consuming. Got a bottle of thin super glue from screwfix and followed a video on youtube (it's not on there now, as far as I can see). I put about 3 coats of glue on, flatted back and polished, then repeated that 3 more times.
It's been on there about 4 years with La Bella roundwounds and whilst there are marks they're just fine surface marks. You can't feel anything running a fingernail along them.
