A line mechanic was informed the md-82 aircraft he cleaned and removed a 'blue' streak from the forward lavatory exterior service panel returned later with a new leak at the same location. Lack of any required documentation in their logbook or in their periodic service (P/south) check; led to difficulty identifying a leak existed.

Narrative:
I was called out to my first aircraft to remove a blue streak on the forward lavatory service panel by an FAA inspector. I removed the dry streaking with the approved cleaner. The FAA inspector asked me if I saw the streak. I told him I did. I told the inspector that when I inspected the lavatory panel there was no ice or liquid present at that time. I told the inspector I had intended to return and reinspect and clean the panel but was distracted by my second aircraft check that I had forgotten. The inspector then asked to review my logbook entry and sign-off on the log sheet. He then asked for my license info and told me he might contact me at a later date. At that point our contact was over. I remained with the aircraft until it departed the gate. I was contacted by union representative telling me that the md-82 aircraft returned later that day with a new blue streak at the forward lavatory panel. I believe the periodic service (ps) check paperwork; and not being documented in the logbook led to difficulty in identifying a leak. The cleaning of the streaks is not being tracked. [Suggest] documenting the cleaning of blue streaks on aircraft exteriors to identify possible leaks.
