The car wash hit our van extra hard on our old caravan and the lens is open at the bottom and the bulbs don't stand a chance to the weather elements. I've looked around on the permatex site but for something like this where else do you go but here ... plus there 800 # is down at night. Loctite is another option. My thought is it's got to be thick enough to make a seal all the way around versus super glue which is hard to use, doesn't stay where you put it and won't make a decent seal imo. What color permatex would be go for plastic on plastic application? .. or Loctite Thanks all who apply.
