Advise is going to be difficult IMHO when your looking for “close to original” since we will not know how close your aiming for.
Interior kick panels are molded plastic and not painted
Gas pedals were not painted and the brake and clutch if present were dipped in semi-gloss black for the bottom 2/3’s (approx) of the arms
Textured rattle can for the trunk would not even be “close” for the original trunk finish. Like the engine compartment (based on your description) there is no short cut to a nice finish look.
You will likely find allot of different opinions on your choices for the engine compartment and engine paints especially since you appear to be focusing on rattle cans
Sure others will offer their insight from their experiences
You’re right. I should have been more specific and noted up front that this is a driver car. I will leave the trunk and some of these other items to be “someday when I have the bandwidth” projects to do them right someday. Thanks.
Did not mean to be harsh in any way. Over the decades most of us on forums have seen new members or owners start out in one direction only to change their minds later. Costing them money, time and even disappointment to the point where they sell the car and find a new hobby. None of my cars are perfect and most have something that I choose instead of making another choice.
They reflect my plan and ideas and I use that plan/goal to answer every question and choice going forward. Same thing happens with drivers, concours and modified cars I’ve done.
One I didn’t respond to was the black detail on your molding. For what you appear to be doing any decent semi-gloss black will do. Most are going to flatten over time and exposure to the elements and UV light.
Again good luck with your choices sure many others here are or have been in almost the same spot you are and will willing offer their experiences
