I did mine without even touching the paint, just need a bit of common sense and a steady hand, if it does splash on the paint, wipe it off quickly... I turned my frame upside down and blocked off the cut off seatpost with a coke bottle lid and poured the caustic soda in carefully through the bb shell... simple...
i tried to block it off with blue tack, real shame it ruined the paint, maybe it can be retouched? dont know.
