Yesterday I've started color restore project on my super classics.I took 16 as it is in the "worst" (still very good) condition compare to bass and tom.I used T-Cut Colour Restorer, put on wrap and left for the night. Today morning (6 A.M. :D ) buffed residue away.First two pics - beforeOther two - afterYou can still see the difference of wrap under the lug, (and some heavy spots didn't went so much away) but discoloration is not such significant as before...I think it's worth to try.Beware...this thing has a seriously irritating odour. Use it only in ventilated areas, the best - outdoors. I did the job in the basement and had to vent all clothes for the night and twice shower the skin to get a rid of it.I will update my project later on.
