Hi, Murphy. Fisheye/cratering is usually caused by silicones and I was wondering where they might have come from. I have the feeling that some tack rags actually have them. The only "sometimes" cure that I have found on a substrate like fiberglass is a thorough rinse with acetone, but I have no idea what might work on wallboard/painted walls. My best guess is a sanding to remove the craters, then a primer like BIN or Kilz, then repaint.
As far as the RL paint, I have not used it but there have been at least 2 other posts with complains about this particular product. One person had to apply 6 coats to cover. Sorry that I can't give you any more info on the RL paint and I'm sure that I will not be using it.
