[pianotech] Plate finish problems

[Greg Newell]

Dale,

                I just took a two day class on finishing and touch up from a
guy named Greg Williams who put on this class together with my local Mohawk
rep. This guy was really good and knew his stuff! He worked for Mohawk for
something like 28 years and now teaches classes on his own. One of the
things that he talked about was a professional refinishers forum on the
internet. I’m guessing it’s much like ours if you can find it. This guy used
to give classes at our conventions years ago. For those who monitor this
list from our home office, he is available to do that again and would like
to if there is any interest. Top notch knowledge. I’ll send him an email and
ask if he’d like to answer your question.

  Esteemed Techno- crats
  I'd like to pick your brains. I need some help.
  Because of the nature of our work we refinish a lot of plates every year.
  We often get the spray canned special  paint job and other times quite a
decent finish but aged and other forms of stuff which needs re-whatevering.
 But right now I have a Stwy  B plate & the second finish that was applied
previously  is very thick and chippy and comes off easily in places  and the
other half won't no matter what. Trying to sand it makes a hodge podge mess.
No  matter how well you might feather all the edges it  usually ends up
showing up even through the new finish.  We use acrylic primer and top coats
with gold followed by clear coats.  I have sand blasted two plates which
takes of the Japanning/ porcelain under coat. I hate to go this route but in
this case I'm stuck. 
  So...  after the blasting it's a matter of using some type of primer to
fill and smooth. I'd like to hear from anyone who has suffered in this way
  So the question is... I would like to find a bare metal sealer/finish that
flows and fills and sands easily.  My thought is to locate something you can
just pour/spray on and let it flow out.  Similar to polyester.  Get the
idea? Hey any ideas welcome
  Thanks
