Well asumming your car is efi not a lot (engine wise)
You can change the spark plugs, change the fuel filter\s, oil filter (which you should do when u do an oil change anyway). Air filter, spark plug Leads if fkd.
And may i ask why you want to paint ur wipe blades? get new ones there like $10 if that.
that should do ya.
and u can use the oil that u get for your car for the hinges just dont go nutz a ver little bit will do.
