First welcome to the site - hope you find it useful
One challenge with marks is that you need to find sources that match exactly you cars assembly plant, options assembly date and all options for many of them and even then many marks will be different so its suggest that you don't copy from other cars except of those that were typical or normal for most cars.
Also before you worry about paint be certain that every other detail is 100% or as close as possible since paint marks will only work to highlight your cars short comings and will look odd that you spent you time placing paint marks on incorrect parts
Your car before restoration is your best and more accurate source for what was originally applied second would be your cars buildsheets
I hesitate to show allot of paint marks on the site since we've found that others will just copy them and apply them to just about any car with no concern to matching any of the details mentioned above even not reading the accompanying captions posted with the pictures. So rather than tempt those owners or builders I have chosen to limited the temptation by doing my part
Yes there is at least one book or brochure that was printed many years ago that I can not recommend and when I meet owners who ask questions related to its information I suggest that they toss it since it will produce more questions and issues that its worth IMHO
I should be posting a new article for the site in the next week for proofing on Paint Marks. Not focused on what are the correct marks for the thousands of different combinations but more of a help as to what their purpose was, colors used, places to find them and more
