damn, i'm wrong. car covers yata.
well kung car covers, get something na walang internal plastic lining (yung parang raincoat) so that it will not get brittle sa arawan. get something too na porous, meaning, air inside can get out of the cover. this will protect your paint from being stained by the "sweat" in case it rains tapos biglang aaraw.
i really don't know where in banawe, but you can get good quality car covers in ace hardware or in tru-value.
