In my line of work I run into alot of copy right issues.
So long as you are not trying to copy the decal sheet and sell it, you are not violating copyrights. What can if at all be copyrighted would be the artists representation of that piece of art. i.e. if there was a piece of nose art on the decal sheet or a logo, that you copied, his or her version of that nose art would be the copyrighted piece of art. But again not a worry since you are not selling them. Typestyles or fonts are not copyrighted, (font names can be). Icon recognizable names or words can be copyrighted. i.e. the words Star Trek are not copyrighted but the words in the typestyle used by the production company are.
Lampooning something (mickey mouse flipping somebody the bird) is covered. Try and squeak that by the empire of the rat and corporate assasins will come to your house and shoot your dog. It is a matter if they feel it worthy enough to pursue. Disney thinks everything is pursuable and does so with impunity.
(BTW Mickey Mouse goes into public domain next year, unless Disney wins their suit to keep it protected)
Copying images is a different story and again is warranted only by what the pursuing company is willing to do about it. again an example would be if you are making a diorama based upon a photograph. You win an international contest with it and create a career out of modelbuilding based upon that diorama and award. THe guy that shot the photo may hit you up for a royalty check based upon your fame using his image. (Laws have changed recently for intelectual and creative properties). If he thinks he can get more out of it than the pursuit costs it could happen, but in all honesty in this case you have better luck licking a shark and walking away not tasting fish.
The other case would be recognizable icons without licensing. i.e. the comic strip characters Calvin & Hobbs (got asked to paint some nose art once with their image) The guy that created C&H does not license his stuff. So anything copied is pirated. Therefore hot. But again if you are not profiting from it and it is a one off, then no foul.
Most stuff that would show up on vehicles etc. are considered public domain and do not have issues. But there are some instances that care should be taken. It is not likely that any issues would arise unless you were copying other peoples recognizable work and trying to make a profit from it.
So now you guys probobly know more than you ever wanted to, so I'll go back to painting my models now....
