Hello,A couple of questions on the refurbishment techniques/kit.What type of sander to use? - Random orbit and 1/3 sheet sanderI have a palm sander that seems to work well but wanted to cut down the time this takes to use. I do sometimes get the pigtails mentioned. - this happens if you use an orbital sander. Finish by sanding by hand to remove these.For polishing do you apply Hyfin to the bat and then polish or to the polishing wheel and polish? - apply polish to the wheel.Thanks.
