Basic question oil vs acrylic

Submitted to Archive: All About Primers

Please excuse this very basic question.
It will further my understanding and ability to chose product to project appropriately.

So I have both types of Bullseye 123 primers in my paint supply closet.

Why would I chose using one formulation over the other.

I confess I tend to use acrylic more so because of the clean ups.

Thank you Kendra!
