the hole in the roof needs a patch of aluminium bonded over it using sikaflex. filling such holes is possible but the heat in summer andcold in winter will make the filler expand and contract at a different rate to the aluminium around it so will eventually crack,
the aluminium corrosion is a well known problem caused by osmosis. the only solution is to clean the area back well and fill all the pin prick holes. then use aluminium etch primer to seal it and then top coat to match in. Paint can be matched at many motor accessory shops. take in a correct coloured part and they use a meter to read the colour then make up rattle cans of matching paint
