I need to change the bulb on my light, however the screw holding the enclosure in, feels like its just going to chew up. I'm only a DIY person. What are my options? are there any tricks i've not thought about? Or do i have to drain 4 ft of water out of it, and go at it with special tools.
Normally i'd use a grip paste, and if still no joy, then a speed out / drill / extractor, but all this being 2 ft below water doesn't leave me many options.
How common is it that the screw that hold these enclosure in stuck ? Perhaps there's a trick or two some may care to share. Here's a pic of the said screw.
