I’m just about to put the final wax finish on a project. A mate of mine has offered to lend me his Festool Rotex 150 Sander/Polisher to buff it up but as he only has sanding discs for it, I would have to buy the relevant polishing disc. What I would like to know is, is the Rotex a decent tool for the job and which Festool disc would I need to buy?
