Plate Removal & Spraying

[Marcel Carey]

I've been told by a rebuilder in Montréal that using matt finish laquer does
not alter the color the same way as the glossy finish does. Now I haven't
tried it myself, but his results were nice... but not glossy...

I have had some troubles when trying to put a top coat of clear lacquer over
the gold - using a non-lacquer is likely a good idea - someone wrote about
shellac, perhaps the best idea of all.

As much as I like and find many uses for shellac, I wouldn't consider it the
best choice as a top coat for a plate.  I would worry about 
1. it being less resistant to marring (from tools, paper clips, pens, hair
clips, etc) and to spills than many other finish choices; 
2.  I find it doesn't lay nearly as flat as other sprayable finishes; 
3. is generally only available in gloss (you CAN create satin & semi with
the addition of talc); 
4. had better be pretty fresh if you want good performance; 
5. and even the palest blond shellac will color the gold to some extent,
although that may not be undesirable.  
 
While shellac is clearly a superior choice to many finishes in some
applications, I just think there are too many superior alternatives to
shellac for clear-coating a plate.
