Yea I know the thread title is odd!!

Well finally started to but bit back on my mk 4 bonus shell. As it's not a n erst shell some of the holes in the engine bay are not drilled out, examples include ecus and the hole for the washer bottle. The shell is actually an early mk 4 whereas my erst was 90 spec. Could someone give me a steer as to the best way of drilling holes in a freshly painted shell? Also what's the best way to cut out the hole for the washer bottle neck??
