How to paint chassis and interior

[Hedgehog]

I'm about to paint these parts on a proyect but I wonder if I should primer them? In the interior parts such as the dashboard

Only time I bother with primer on chassis or interior parts is if I've done some mods, like shaving interior door handles, or filling sinks in a chassis rail. Then primer is mandatory, as well as sanding and re-priming the areas as necessary.

If parts have no mods, I scrub them with Comet and an old toothbrush (especially inside corners), carefully dry, and paint away. No problems so far in the 5 years I've been back in the hobby.

I always primer everything. It makes painting so much easier.

Been building models for about 50 years. I used to not prime back in the day but for the last 20 years or so I always prime.
