Continue preparing the windscreen and the sunroof by redrilling all the holes with a
4.5mm drillpiece. This is 0.5mm bigger than the rivets and will stop any cracks in the
lexan screens from developing due to engine vibration or temperature change.
Using a countersinking tool, take the sharp edge off each hole at the top and bottom.
This will stop cracks from developing in the screen.
Use a de-burring tool on the top and bottom of the screen and roof panel to give a nice
chamfered finish.
