I've been filling/sanding/priming/sanding by Big Brite clone and need to make a note to myself: Next time, buy something other than Rustoleum Painter's Touch Ultra Cover 2x. I have had this problem before, but only remembered after I repeated my mistake. That is, the primer develops hairline cracks that defy filling with additional coats. I think I blamed this on the undercoat the last time but, this time, I shot the primer on unfilled LOC tubing and bare wood. I shot two coats, one a half hour after the other. This is well outside the 'coat before 1 hr or after 24 hrs' window. Since it doesn't occur over the entire surface, I suppose it has to do with the thickness of the coats. I generally lay paint on too thick, but generally do this on purpose with primer. The fix is that I have to scrape the cracks with a scribe or hobby knife and then fill them with Fill'n'Finish before recoating. In any event, in the future I will merely use another brand. Plastikote has been good to me.
