By the way, smoothing the cowl is a LOT of work due to the amount of welding and the amount of careful grinding and sanding. If you're just looking to keep out (MOST) debris, consider something like what I saw on a truck at Carlisle (below). If I went that route, I think I would take the extra step to line up the little holes with the cowl vents.

I’ve got those cowl screens on my 72s. One of the rare items I’ve purchased from LMC. I had them powder coated black before installing.

A copper magnetic plug weld tool is a lifesaver when welding thin gauge steel.
