Back to the tail light leaking issue, which I thought I had fixed once and for all. Removed the tail lights this morning to make sure leak fix was working and it did, but found that the water was migrating into the screw holes and some, but not all were soggy and stripped. I am drying them out now and will probably use "Get Rot" or similar to plug and coat. Also will dab a little silicone sealant under screw heads before tightening. Hopefully I can forget about this issue after messing with it this time.
