Hi, when painting the panels after roughing up a little with a 220 sandpaper, do you recommend using a PVC primer first before the water-based acrylic or latex paint? It is not mentioned in the video on how to paint the panels which is why I am masking. We do have three children with an active household, so I’m just curious if the PVC primer would add some longevity or not necessarily. Certainly don’t want to waste the time and money if it doesn’t add much
