I am working on my first project. It is the base shelves for the modular desk and I have all my boards cut but I dont know if I should paint before I put it together or after I put it together. I got contradicting advice from two knowledgeable sources so I am curious what this community has to say. I will be using the kreg jig to make pocket holes for assembling it if that makes a difference in the options at all. THANKS GUYS!
