1970 Swinger 340 Hemi Orange 4 speed
Thanks! I use U-POL copper weld thru primer. I've tried the other brands (don't get zinc) and they cause a lot of sputtering and you have to end up turning your welder up to weld thru it, which gives burn thru and warpage. This stuff gives little to no grief welding thru.. I still like to take an o ring pick and scratch it away where my plug weld hole is, but it really isn't necessary with this stuff.
