Here's a detail of the foam seal at the bottom of the shroud. At this point I also added foam all around the top of the shroud (not shown in previous pics).





I wanted a durable finish on the shroud that didn't need the maintainance of bare aluminum. So I painted it VHT wrinkle paint baked in an oven. I can run my fingernail against this paint enough to file it and it will not scratch.
