Picking up the thread, but with a slight twist: is it possible to use gold paint/gilding on a fully finished concert grand sound board to hand apply a design? I’ve seen a beautiful, older Salvi whose unadorned soundboard has aged to a lovely carmel color. I’ve also seen gold tendrils and vines painted on older Minervas and wonder if an artist could apply similar embellishments directly onto a finished soundboard without having to sand down the original finish to the wood to apply the embellishment and then reseal?
If one painted directly onto a finished soundboard, would those embellishments then need to be sealed? I worry the extra varnish could impact the sound, but insealded painting/gilding would be unprotected. Noodling over potential ways add a bit more interest to a currently unadorned soundboard.
