[pianotech] Polyester Finishing

[Michael Spreeman]

Oops. Apply the Meguiar's with a Meguiar's W-9000 finishing pad. (yes, it's Meguiar's, not Maguiar's. Sorry.)

I use the Menzerna 2.5 pound polishing compound bar with four 12" buffing wheels stacked on a Hitachi 7" polisher. They make a coarse and fine compound. They say the coarse will take out 600grit scratches. I wet sand down to 3000grit and only use the fine compound; it's faster and gives a much better final buff.  Finish with Maquiar's #5 Professional New Car Glaze to remove any remaining compound scratches (available at automotive paint stores).

For all the Poly repair folks:

I use Koenig compounds with a large wheel to buff out minor scratches.  I'd like to ask what any of you use to moisten your compounds if/when they start drying out?  I'm using the DD3, 2L, 16 compounds in small tubs (500ml).

Thanks folks,
William R. Monroe
