What primer to use

[Jacques Reed]

I have been using the generic term "red primer" in this thread. The actual colour of the primer I have seen is more a reddish brown.

Red lead primer was banned even in my early days at sea in the 70's but seafarers still called any primer "red lead" for many years thereafter. It was a more red colour compared to the reddish brown primer I have seen on my vehicle.

Doesn't prove vehicle paint didn't contain lead but obviously they were differently formulated paints.
