I first place a tarp on the floor under the piano, I have never had a spill, but it only takes one! I just use the cheap 6X8 vinyl tarps you can buy at the home repair stores. </div> <div>I buy my CA from my local hobby shop, it comes in a sealed bottle, 2oz and 1oz. in several vicosities, I use the very watery one. The hobby shop has tops similar to the oiler tops at a fair price so I have those but I've found if I cut the tapered top open at the smallest point, I don't need them but I have them and occasionaly use one. In grands I remove the action and spread a thick layer of newspaper over the keybed. </div> <div>The only other difference is I prefer to allow it to sit overnight and in winter(I'm in Wisconsin) I make sure there is adequate humidity available for the proper cure of the CA. Open pans of water sitting nearby with a fan blowing across them seems to be sufficient. I find if it sits overnight it is fully cured and I don't have to deal with the strong vapors, that much CA will have your eyes watering without adequete ventilation. I usually schedule the treatment as an end of day appointment with a next day tuning. </div> <div> </div> <div> </div> <div>The tarp is from years ago when we still used pin dope, I hadn't bought a tilter yet. I had laid a Jesse French spinet down using a couple of 2X4 blocks to rest it on. I was treating the entire block and remember thinking how awfully thirsty it was I had refilled the syringe I used for about the 7th or 8th time when I looked to my left and saw a puddle of Pintite forming underneath the back of the piano and spreading outward on the customer's celery green carpet!! I was alone in the house until just that moment when she returned from her grocery shopping, saw the puddle and calmly said " I guess we'll see how good that Stainmaster carpet is"! I stood the piano up, got a tarp out of the truck, came back in and helped her soak up what had leaked out and that carpet saved my bacon! </div> <div>I have since never treated a pinblock with anything without a tarp under it!</div><br> </div><br>Mike<br clear="all"><br>-- <br>A great many people think they are thinking when they are merely rearranging their prejudices. <br><br>Michael Magness<br>Magness Piano Service<br>608-786-4404<br><a href="http://www.IFixPianos.com">www.IFixPianos.com</a><br>email <a href="mailto:mike@ifixpianos.com">mike@ifixpianos.com</a>
