Detail preserving food safe coating for SLA resin prints?

I'm looking into SLA or MSLA printing to make master models to mold food grade ComposiMold over, for short run, limited edition chocolates.

After casting a few molds, the 3D prints would be discarded, and after the chocolate run is dune, the molds melted for reuse.

Is there a spray on food safe coating that won't fill up fine details and can withstand 130 degrees Fahrenheit a few times?

Even if I don't do this myself, I think it would be a good money maker for caterers and boutique candy shops. Think of a wedding where every guest gets a couple of custom chocolates with the happy couple's names and the date. Or fancy birthday parties with the person's name and date. Anniversaries, Happy New Year 2027 etc. Corporate merger events with both company names. Any occasion or event where it would be far too costly to do something like CNC mill a multi cavity plastic master to vacuum form a mold that will be useless after the event date.

If this concept isn't patented, I'll call it public domain here 09/24/2026, so anyone who wants to use it to make money can do so.
