Hey there boydo I was recommended to contact you for tunnel polishing. Its actually for my boss told him I would try and get some info for him. I believe its a 153 doo not sure which model but fairly newer. Just wondering what you charge and if/ when you would have time? How long it takes to do? Contact info other then here? Not sure if he's a member. Also while I'm asking how much for a 13 pro 163 tunnel and boards? Thx in advance. Oh and just an edit I'm not sure if you have different polish levels but he's looking for a mirror polish. As would I thx again.
