Me too!! LOL!! As I think back, maybe some clear coat had settled on that particular piece because I cleaned, wire brushed, pre heated, set the welder to max clean to bury the impurities (not a common practice at my shop). Yeah I felt like I was asking directions because I was admittedly lost. LOL! When you weld anything, material and filler rod need to be clean to get great results. Aluminum is particularly picky about being clean before welding. Just don't use brake cleaner. If you do multiple tasks in your shop or work space like I do, keep your metal covered and your filler wire out of the elements however you can.
