Just completed my build - 310S SV - and didn’t have to cut anything other than the rear wings in order to connect the radius arms; no dremel needed, just a hacksaw. No touch up paint provided with the kit. As Tony’s note, wiring the deadlights is painful. If I were to do it again, I might consider cutting the wires and re-soldering after threading through the brackets as I had particular issues with damaging the pins. Make sure you get a copy of the new Assembly Guide, version 1.2! David
