I need to replace one of the tail/brake light fixtures and want to caulk around it (and have to cut the current off). What's the best caulk to use? Recommendations? Thanks
Butyl tape and Lexel caulk. In a quick fix moment, I put some Lexel over silicone that had pulled away between trim and the camper. I went back to it a couple weeks later, to properly fix it, and the Lexel was definitely adhering. So, I left it. More than a year later, it’s still good. Maybe some things will stick to silicone.
