Plate Removal & Spraying

[Farrell]

Hi Mark - thanks for the input. I did have shellac durability questions in the back of my mind. What do/would you use as a clear satin top coat over gold (metallic) lacquer?

Thanks.

    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.
