      nice cap and bung... be aware though

      i tossed the bung in, i didnt check anything in particular, but it definitely seemed to react like stainless as soon as i lit up on it, so i grabbed a 309 filler rod as soon i saw it... and then it welded beautifully. just wanted the buyers to be aware
