There are several glazing or "spot" compounds for filling
sand scratches and pinholes in a primer before your wetsand
and color. Some of those are red. The one I use is bright
green. Mostly it should contrast the primer color so you
can see where the layers are when wet sanding.

That's red but it's not lead. Mine's not even red:

When I was young there was a lead brick red color powder
sold as 'red lead' by weight at hardware stores. The clerk
scooped it into a paper sack on the scale and I rode it home
on my bicycle. My father mixed it with linseed oil to make a
metal primer for downspouts gutters and the like.

This is lead tetroxide, Pb3O4. I doubt you could buy it at the hardware store today. It is naturally that color, and used to be used as a pigment as well
as as a metal filler. I know that red lead primer is still available for industrial use but again, not a True Value item any longer.
