[pianotech] Plate finish problems

[Greg Newell]

Dale,

                Here’s what I received back from Greg Williams, the finish
and touch up teacher from Mohawk.

 

Greg, for a quick answer without asking for more detail from him; there are
automotive products such as Feather Fill (by Evercoat), a number by Bondo
and other vendors that will do the filling with the requisite adhesion to a
well prepared substrate. It is important to have an unbroken final primer
coat after the level is done.  That is, when you have done all of the
filling and sanding to level, a final primer coat will be applied and sanded
smooth without breaking through to a subcoat.  No more spot filling is to be
done at this point.  If additional spot filling is necessary, you will need
to apply another full coverage primer coat.

 

I would use catalyzed (requiring a hardener) products to avoid subsequent
shrinking from the evaporation of solvents found in air dry products. Look
through this website for more hints

There are pourable polyester and epoxy filler/primer/feathering products
available from automotive refinishing suppliers.  I imagine that extensive
sanding will be necessary regardless of how the product is applied in order
to get a really good looking final finish. 

 

I hope this is helpful. I enjoyed talking with you in the class.

Thanks Ron/Terry/ Al/ Greg and all who responded with suggestions.
  Ron...To be clear I wasn't about to leave any of the old finish on.  Ever
things gotta go before the primer/magic wand/ filler/whatever is employed.
I wonder if the original japanning process is difficult or that specialized
that it couldn't be replicated for plate jobs.
  Just think blast the crap off every plate and then pour on the japanning
and start over. 
  Something else to add to my wish list along with a keyboard pounder.
