Lol uv lights all hf Braun brand uv lights and any brand at any store up north are sold out apparently everyone's buying them to search for these things locals call "yooper stones" on the beaches up here. They do have a massive surplus of oil based uv leak finder oil everywhere here hough. Meanwhile I just want to find one uv light somewhere to check for hydraulic leaks and actually see newer hydraulic fluid in a sight glassAnyone have any experience with the harbor freight brand oil based uv leak detector fluid you use with the hf Braun brand uv light?
