The ring of ice on my PC does bother me a bit. I am not a fan of sled wraps, but has anyone tried vinyl on the tunnel to keep the snow from sticking? I have a cutter and used to do decals for a living, I have a roll of clear vinyl here, it would be pretty easy to apply a layer where the snow likes to stick around the exchangers. Maybe pull the bumper and run it underneath? For that matter, it wouldn't be too hard to draw up the file and cut them on the cutter. Does it help?
