I'm a bit worried about this so here it goes. Basically my Shergold has become grubby and dirty and I want to polish/clean it. Problem- the bass has the original finish. Because of the bass' age (32) the finish has cracked and so I'm worried incase I strip the finish off. The Shergold site is not much use and with Shergolds being so rare I haven't found any information specifically for them. So, will I do any damage if I use an ordinary polish on my Shergold (in this case Dunlop Formula 65 polish)?
