isnt he talking about knocking the dags or slug off ?

that still will not work, slag is the metal thats melted together sandblasting it will only remove weakest bits of slag, also TIG and MIG welders do not have slag, just the peno that has burnt through pipe which basically is just the back of the weld......

its better then being in your turbo or motor i guess ??

haha yer man id guess that 2
