Buffed out a 10' tank from 800 grt to 1200 and then Novus 1 and 2, got it to look like new!! Didnt think I had that many hours but I didnt keep track of my time. good luck with the sale
Anyone who has ever buffed scratches out of a monster tank knows that it's well worth paying someone $20/hour to do it for them. A tank that size (if done correctly) would take around 40 hours to do all four sides. Bump for a good deal.
