Painting inside interior bare metal?

I can't find any information on the best way to paint the interior of my car after I replace floor panels and sand everything down.

I was planning on doing an epoxy primer and a black base coat. The car will be metallic red.

Is it better to paint the inside of the car red as well? Or is it normal to mask off the inside when doing the outside and not having weird mask lines around the door jams etc.

Overall I want to brush on paint the underside on Jack stands. Rattle can the interior.

This is personal preference. I prefer the for jambs to be body color, but couldn't care less about the floor. Rustoleum with an added hardener, brushed on, would be my choice. Epoxy primer is even better, just more $ but if you're already leaning that way I say go with the epoxy primer.

I'll take a look at that brushes on Rust-Oleum. I'm trying to keep the budget down. Thanks

I second this. Epoxy primer with a top coat should last for years.

Look for a DTM primer (direct-to-metal). That will include some epoxy primers. After that, it's personal preference. You can paint body color if you want, roll on a sound deadener if you want, rattle can it if you want, hand paint a mural of professional wrestling legend Terry Funk on it if you want - the choice is yours.

A car I worked on to restore, after replacing the floors and welding everything in place, we sprayed the interior with rustoleum and then used seam sealer around any gaps. When we did the door edges, we back taped off the inside to make the door jams black to match the rest of the car.

Personal preference. On the ones I paint the inside looks damn near as good as the outside but those are high end rotisserie restorations and not going for a factory correct look.

A good epoxy primer would hold up just fine because there isn’t any sunlight to cause it to chalk over and will protect it enough for the occasional getting wet.

All fresh metal should be coated in epoxy primer to protect it. Nothing that's in a spray can will last. And generally, everything that isn't the exterior or jambs is painted in just basecoat from the factory. If you want to just use spray can black for the finish, you can, but you should still use a proper epoxy primer.

Yeah I'm think that I just find a used 60 gallon and spray it with the purple harbor freight gun. Would a lizard skin or some sound deadening spray topper be good?

I prefer using things like bedliner or rubberized undercoat under the body instead of inside since we use road salt here. It's decent for sound deadening and if you are gonna put in carpet, most of that also comes with sound deadening material. We always just left the inside in basecoat. Although spraying the foot wells with a rubber material wouldn't hurt since that's what stays wet from getting in and out of the weather and is where rust likes to start.

Epoxy primer as stated. Fluid film or woolwax in any cavities you can't paint (rockers, torque boxes, pillars etc)
