Do you have a picture of this welt installed? How is it secured to the cowl? Is it a specific quality/thickness, or could I cut a strip of heavy canvas, secure it, and then oil it?
Also, on the topic of "hood"... for our '48 Special Deluxe, we need to make the center seam of the hood water tight. The Service Manual says "Apply Heavy Sealing Putty to the underside of the hood around the chrome strip clip openings.", but not sure where they mean. It would be simplest to apply a bead along the top side and hide it with the chrome, but would that cause any issues?
Here are pictures of the underside of our hood, and also the top view with the chrome strip removed.
