When I was working on "blueflame" speed record vehicle I know that modeling and texturing will be quite nice and easy with only one exception:
Text decals scattered all over that car. The challange was that fonts doesn't look familiar too me so I know that if I want to make that texts highresolution I have 3 options:
1. Find by any chance that fonts
2. Trace them manually using curves which could be time consuming
3. Use orignal parts from photos and use AI upscaler which could be tricky

Option 1 was most promising but how to quickly determine that exotic fonts? The solutions was to use AI font finder tool in my case www.myfonts.com
That tools gives you list of fonts which look promising and quite often 4th or 5th position on list is the font that you are looking for but it is huge time saver.
So if you have similar work to do you should definitely give it a try :)
