not being of a violent nature, I,ve almost killed neighbors cleaning their cars w/ armorol. silicone based products are the scourge of all painters, as silicone molecules are so tiny they can travel over eminence distances on air current up to a 1/4 mile. wd-40 ? no different . they can not be far enough away from your paint area. At one time I experienced the crater covered clear coat nightmare on several occasions. after banging my head relentlessly on the wall , I found the problem came from a trucking co. next door. the particles in the diesel fuel traveled several hundred ft, through the intake and air make up system, weaseled their way through the intake ceiling filters and comfortably rested on a job in progress. Clear coats have always been more prone to problems due to contaminants than color/ base coats. fish eyes are by far the mot difficult problem you can have while painting . finding the source can drive you to insanity and bouts of paranoia (some one in the shop has to screwing with me). seriously, Ive had that cross my mind. correcting the problem usually is through the process of elimination. If its not coming from the vehicle, there can be dozens of other sources.
