I'm not really sure why it would be necessary to plasti-dip or electri-tape-dip these ballasts in the first place. Then it just looks like a blob of goop when done. That isn't even where the water usually gets in (I wouldn't think), since both covers on Philips/Hella ballast have gaskets under them. The water is most likely to get in through the vent, the electrical plug, or at the crimp where the HV cord leaves the ballast case. If I wanted to seal a Philips/Hella ballast, I personally would only use the liquid electrical tape around the HV cord's crimp at the ballast case, then I would use silicone grease and lubricate the rubber O-ring seal, and pack the socket of the 9006 plug with the silicone grease to guarantee a good seal against moisture at the plug. Then if you were really worried about the side panels of the ballast leaking, I would rather just take off the panels, and smear a film of clear silicone sealant on both sides of the gaskets, and tighten the covers back on (not to overtighten and warp the covers), and that would seal the unit very tight in every aspect except for the vent. So you must always make sure to mount the ballasts so the vent is facing down, so gravity wont ever bring water inside through that hole. Or, if it can't face down, and it would be near water, then you could glue on a baffle over the venthole that would make it have to go around a corner in order for the splash to get in around the vent area. But I think the easiest place for water to ever get in is through the vent.
