I used Topoil to finish six chacuterie boards for Christmas presents. I am very pleased with the results but I was not pleased with the lack of instructions on how to apply it. On the first two boards I applied a first cote that was relatively thick, resulting in bubbles that took more than the usual effort to sand out. Sanding between coats is my usual method, and I recommend a thin application for the first coat.
One of the few discs that really allow dust removal, they seem to last for quite a long time and they remove stock well.
