Hi, Mike: I haven't had problems with shelf life of the polyester. I have some that is years old and still usable. There is a gel polyester for vertical surfaces, and comes in a tube. I have one of those that is so old I can't remember when I got it. Still works. YMMV. One thing that is helpful is a good strong light. Switch it off when you show the customer! Just kidding.. Always use a flat sanding block DAMHIK. If you use factory polyester, you'll pay a fortune, and it'll be worthless in a month. Ruth's polyester has to be color matched to the old finish, but it works great. It's thinner, too, so it will spread easily into nooks and crannys (inside your dam) so you won't have so many bubbles and voids. Mix things up carefully, and follow the directions exactly. As far as the kit is concerned, you will make it up in repairs. Gearing up for poly may cost some $$, but you have to be prepared to commit to the whole nine yards. If you do, you'll make more per hour and be in demand. In today's uncertain economy, it's good to have more arrows in your quiver. Now, if someone can show me how to repair the veneer under the polyester and make it look AS NEW, I'll be forever grateful.

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.
