[pianotech] plate finish

[erwinspiano at aol.com]

Hi Joe
  I sue an acrylic lacquer and it has some body to it so as long as I retain the same color mixed thoroughly the chips on the hitch pins are easily repaired with reasonably good appearance.same in the web area. The acrylic is not a brittle finish as it contains plastic-sizers
(ER however its spelled)  It does get harder as it cures over some weeks. The beauty is it doesn't chip very easy aaaand... applying it is idiot proof...which explains why I use it? LOL
 In the past we covered the hitch pins with rubber tubing but the cows needed milking and it just took up too much milking time puttin em on.....not really

Thanks David. I will consider your suggestions.

 

Now let me come at this by saying that in the default condition chips and
ripples are unavoidable. Those of you for whom this is not the rule, please
weigh in. But given chips that now require touch up, how do you proceed? I
have never been happy with this kind of touch up, especially in the web area
where you are now working around new pins and coils.

 

In any case, all I have really been able to do is brush in some gold
lacquer, but this doesn't fill the chip, it just colors it. A bondo patch
will require sanding which will scuff the plate beyond the small localized
repair, and now things can go from bad to worse.

I have become quite good at repairing the chips.
