Narrative:
Aircraft X on nov/thu/01 was scheduled for lap inspection. I assisted another inspector with this task. When aircraft came in hangar, it was wet from all the humidity. We had to wipe the assigned areas several times to accomplish the inspection. I was pulled off several times because I was also assigned slat rod ends right&right on another aircraft. I was also being pulled off to answer questions on the 'C' check aircraft, which had forward entry door lower hinge box crack. I strongly believe a complete and thorough inspection was completed on aircraft. Contributing factors were being pulled from job several times and unable to mark where we left off due to wet aircraft.
