I've posted in the past about my troubles with the Florida Sunseeker Pooltone Nicheless LED Lights ( Jandy Nicheless LED Replacement ). Short version: install three new lights, used very little, two quit working and broke at the 'stem' (center red line) and showed corrosion at the internal screws (red circled areas) the next season; out of warranty so FS offered me a discount on two new ones.

As I'm prepping to install the lights for this season, I had a thought that may help extend their lives a bit and wanted to run it past the TFP experts. If I coated the backside of the fixture with Flex Seal spray, would that hold up in pool water? My hope is it would protect from corrosion at the little screws and potentially keep water out of any small gaps or cracks in the housing that would fry the internals. I would protect the threads from getting coated to ensure they screw into the fitting.
If Flex Seal won't work, is there any other product I could try? Looking anything that might extend the lives of these things because once this set dies I can't see investing in more of these type lights.
