Well, I started spraying in the Lizardskin this past Saturday. It goes on pretty well. I had treated rust with converter and rust-inhibiting primer before putting in the Lizardskin. I've used up a gallon of the sound control so far with about 75% complete. I have the door interiors left, and some touchup in areas where I think it needs to be a bit thicker. I've been taking photos, will post some time. I need to order more, and the ceramic insulation. The optional sprayer works well, and is well made. You have to take the time to clean it well though. The cup that came with my sprayer has a tiny crack in it, so I've requested a replacement. Not sure how it got there but I think during its manufacture, because it was there when I pulled it from the box.
