I know exactly what you mean by a "small fortune"
When I brought Amadeus the PO thru in some boxes containing various manuals, brochures, etc and included in one file was a spreadsheet showing what he spent during the first haulout. $28k
which included a total 2 pack spray paint top & bottom, osmosis strip, mast removal & 2 pack paint, ceiling and windows rebuild, etc, etc.
Made me a bit happier about the small fortune I had just spent
