My new led marker lights had a gasket, so I sealed a bead around the outside after screwed in, but put lexel in the screw holes before I screwed it down. No leaks so far. But I have used this stuff to make an almost 2 inch gap bead around metal and it does a great job. I would suggest coating the back enough to get squeeze out on all sides, clean up the bead then screw down with lexel in the screw holes. Word of caution, this will stick to ANYTHING so be careful and wear gloves and don’t inhale the fumes. Standard stuff.
