John B. fired this volley in
:

One of the "secrets of the welding trade" is a can of flat black spray
paint. A quick squirt of black paint makes the poorest weld look good

With that approach, Bondo would make it look "NASA quality". snicker

If I send something out (like the occasional micro-TIG'd job with sub-
1/16" welds, or a casting that has to be toasted for 24 hours before
welding), It comes back as clean metal. Anybody paints it... they CLEAN it
again!
