The Dynacorn parts either come coated with their weld-thru or the standard new part black (probably crappy - primer). Where I was going to weld or had ground, I either used weld-thru primer or in some cases used epoxy primer.
Could I have coated it more uniformly and thoroughly, probably yes........ Much of the framerails gets welded on to install the DSE stuff and what I had sprayed on the inside of the rails was burning back off in those areas. I may coat the inside of them with
