There are many brands of weld thru primer, we use 'UPOL' copper rich ourselves. The weld thru primer is meant mostly for welding sheetmetal together, the primer melts and surrounds the weld or 'hot spot' to conceal the spot from potential rust issues. for welding the LCA areas clean the area thoroughly as it is not an ideal location as it will most likely be overhead and cramped quarters ,and undercoat or paint afterwards. The weld thru primer may cause a problem for striking an arc and will promote spattering of the weld. An alternative is to use POR15 afterward, that s**t is incredibly tough and will glue the lid to the can if your sloppy with it haha, hope this helps
