So thinking of running a test on weld through primers this winter. My idea is t9 take a few pieces of 18 gauge, use copper weld through on one set and zinc on the other, then plug weld them, and coat them in epoxy primer.
Then maybe expose them to the winter, drill out the welds and see which one performed better.
Thoughts?
I would be interested in seeing Medallion rs-512 vs anybody
