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.
