Depends on what you are looking for in the end... If it is not a concour's restoration, you are good to go if you like it.
I am re-doing a '71 vert and will have the engine bay painted in a semi to flat black configuration. Trying top keep the original look on my car. Keep having fun!
I use SEM 28091 Flat black urethane paint.. To add some gloss, which I do, there is SEM 38008 that goes with it.. The paint is extremely durable and easy to mix. I always prime first with a high build urethane primer and if it's thinned to a lighter consistency, you don't have to sand it out.. Just spray the SEM black over it within the time limits specified and you get a beautiful semi gloss finish that will last a lifetime.. I have avoided the Eastwood paint due to the amount of complaints out there..
After seeing your video I just might keep it since all assemblled you only see a few spots anyways. RRRR decisions decisions....Cars going back to medium bright yellow so the gloss should POP
