BM Aura is pretty good in getting red coverage- but the tinted primer is still a good idea.
Believe it or not- with a quality paint- it is better than it used to be.
Muralo makes a red primer that gets it right there right now. my problem with it is that it is a flat primer, and if you are using eggshell doesn't help with enamel hold out ( sealing to make paint sheen full)
