I've had mine done now for 4 months on my pickup zero issues with moisture. I have had my civic's lights done for 2 1/2 years with zero problemes also. if you do it just make sure to clean out all of the old glue where the two peices seal. one side is a channel, U shaped and the other side just sits in. i used a clear silicon with the tapered tip and filled the channel then sat the other peice in (if your careful enough when you take them apart you, the clips wll still hold the 2 halves together while the silicon dries.)
