Wim: I took the class from Ruth a few years ago, its not the class that's costly, its the kit to do the work you must purchase. I did a few jobs and found several things: 1. You must have good eyesight as you are constantly filling, sanding, sanding, polishing, polishing and refining the job to the point where it matches the surrounding area. This has to be done with black as well as natural wood finishes. This can be tedious (but being tuners, we're used to that) and your customers will expect a near perfect repair and as Cliff said, some are very critical. 2. If you don't maintain proficiency, its easy to lose the touch and skill needed to do a good repair. 3. The filler that is used to do the repair has a shelf life of about 6 months and is not cheap. For these reasons I stopped doing poly and sold my kit to another tech. On the plus side, once trained you will have work coming to your door when piano dealers, owners and furniture stores know you are capable of doing poly repairs. And you can almost name your price. It might be a good idea to check with furniture stores to see who they use to get an idea if others are in the business. See you in G.R. Mike Kurta, RPT Crystal Lake, IL
