Last evening, I finished up the welding, a few coats of primer, and undercoated.
Tonight, I was able to spot welded it in, so the next step will be to finish up the welding. I taped up the interior side of the engine hatch, and started to spray a little primer in the access holes. Plan on spraying in undercoating to help with deadening the sound a little. I know I won’t be able to coat the entire inside, but a little coverage should help.
