As was said, PLA is Biodegradable and the two things that make it break down within a claimed two years is moisture and sunlight. So those are the two enemies of PLA and dictate the purpose of your printed items. If it needs to be used in outdoor or moist environments I would use ABS. Raise your temp for better adhesion and increase the thickness of your walls. You could also spray some kind of polyurethane sealer on the inside.

either ABS or PLA - If it is oozing then there is not good enough adhesion between the layers and/or perimeters....
