Go to a real paint store and ask.

I've used Kilz and always hear about Zinsser products. However, year after year, Consumer Reports rates Behr interior and exterior paints at the top of their list. I used the Behr with primer to paint over a dark color (cobalt blue!) with great success. I would feel confident using their primer.

I would disagree with both of those answers but what do I know?

Zinsser 123.

Since you haven’t bothered to provide an answer, what DO you know?

I’ve used Zinsser 123 and BM Fresh Start, both of which worked well.
