Just want to mention that when using strippers with wax make sure temperature does not exceed 90 degrees. If it does so, the wax tends to melt into the pores, causing yet another problem.

There aren't any "waterbased" strippers. There are various water soluble strippers that use relatively benign chemicals to do the stripping. Dyna 2 is essentially a hyper-soap. It wets the old coating to the bare wood, it does it in one application, and because of that fact, it is the least expnesive way to strip a piano. The highest cost input for this job is labor. If you can save one or two applications of stripper, you're saving a lot of time and money. There are side benefits of using a stripper like Dyna 2. There's no wax in it, yet it forms an exterior shell that prevents evaporation. If you fail to remove all the wax from a methylene chloride stripper, you leave yourself open to craters and fisheyes. Dyna 2 is also an effective silicone emulsifier, so it grabs furniture polish that penetrates into the pores. Doesn't always get all of it, but since I've been using it, I haven't had one instance of silicone contaminated wood. I also like the idea of not burning my hands and arms and not spewing forth toxic fumes in the air, and toxic waste into our environment.

Works in 15-20 minutes. About 2 1/2 gal. to strip a typical 5ft.7" grand. A good fit for small shops that don't have room to lay out all of their parts for the several hours/overnight time frame required by the water-based strippers. Yea, it's nasty - so precautions are in order. I still prefer it to the water-based strippers for efficiency in my shop. And remember, I am a LONG-TIME water-base finisher, and do try to avoid the stronger solvents when there are alternatives that work well with my workplace. > >Mark Potter > > >
