Operated Aircraft X. During the preflight exterior inspection of the aircraft I noticed some temporary repairs were made to some delamination in the area of the ADG door. I noticed aluminum 'speed tape' was applied to the area of the ADG door and the speed tape had been applied so that the door would not be unobstructed from opening. The door was taped over so that it may have been prevented from opening up successfully. I notified Maintenance Control. Contract maintenance was brought to the plane and reapplied the tape so that it wouldn't tape over the door. The Flight was then signed off and flown to ZZZ1 without issue.Improper maintenance procedures were performed on this aircraft day(s) earlier that allowed the ADG door to be taped over. Not only was the aircraft returned to service and operated an unknown amount of flights with improper maintenance performed; it also went undetected by at least one flight crew who flew this aircraft to ZZZ the night before. This situation was a safety issue that needed to be fixed before departure. Adding to the stress of managing this event in terms of coordination; making announcements; continuing to contact Dispatch and keep everyone informed; Duty Pilot and ZZZ2 Chief Pilot decided to try and intervene and force me to board the aircraft before Maintenance had arrived. I made the Pilot in Command decision to hold boarding the aircraft until Maintenance had arrived because I know it wouldn't take long to board; and COVID-19 concerns with keeping people confined to an aircraft longer than necessary. We knew we weren't departing immediately and there was no sense in boarding an aircraft in the middle of summer in the south with a pandemic going on until I knew when we would be able to depart. It was distracting to my duties as PIC to have management continuously interrupting my situation and duties with their concerns. That's not the time and place for those to be brought up. Pushing captains against their PIC decisions when they're making sound decisions in the interest of safety and health should be addressed as well as the maintenance repair issues.
Pilot reported questionable maintenance procedures regarding the temporary repair of delamination in the area of the ADG door.
