I removed the alarm siren because of random squealing, no false alarms so far .
also cleaned the drains and all around too, it was not bad , found a few leaves and twigs and 2 wiper nut covers down there , now i have spares :-)
i fitted the 2nd grommet , coated the cowl with macquires gold class trim dressing , the light grey patchy look has gone and it looks a nice even dark grey now.
a good day .
