Grav Belts?
I considered this out of reach (because of price) for the average crewman and also an item not likely to be 'checked out' unless the crewman has a 'work order'.

Not to mention docks and landing pads will likely have convenient gantries and lifts for servicing that could be 'borrowed'
I considered this too and felt that security around ships, especially military ones would be pretty tight. Don't want some terrorist roaming about the hull planting bombs. So again, only authorized personnel and possibly nobody from the ship does 'yard work' and only shipyard crew have access.

Also, craft generally have airlocks and possibly simple gear/hand/foot holds for maintaining the outside hull.
Cycling a airlock not being used for loading/unloading will probably set off alarms. Same security issues. Don't want unauthorized folk getting into your ship.
Again, not saying impossible, especially if such activity is encouraged by those in charge.

Even small robots might be used, explicitly for these purposes.
Hadn't thought of this one. Nice.

For fun I googled 'pilot kill marks' and looks like 'unofficial' - even against military regs - markings aren't uncommon.
I think these examples are not very comparable. The locations are easily accessible without any special training or gear (no vacc suit skill needed, no grav belt needed, maybe a stepladder), little time needed(less likely to be caught), simple supplies (no special paints to withstand reentry or for application while in space). For whatever reason, fighter planes are 'marked' with pilot name, squadron emblem and whatnot but I don't recall ships having much graffiti even though there is a lot more surface area to work with. As I mentioned before, I do believe that in jump space there is plenty of time and easier access (especially for 'hanger' or other appropriate crew) to paint up the smaller craft held inside the jump ship.

Its been my experience that people will often expend their greatest physical, mental and creative energies on the silliest of pursuits... (think 'professional sports' fandom, customized cell phone cases, etc.
Would a crewman who has been in space for who knows how long be taking time to mark up the ship when they get 'shore leave'? Maybe as a dare after drinking with their buddies?
Vile had good points in his previous post. If some tradition of markings is being done IYTU, I would think you need to determine if it is authorized, 'look the other way', or discouraged "not only are you going to clean that off, you are going to be cleaning decks the whole time were in port!" because it could determine the quantity/detail of markings and also turn into some interesting role playing, like getting caught painting the ship.
