This video is a step by step illustration of how to avoid unnecessary lap sealant when installing and sealing a new skylight dome on the rooftop of a Beaver motorhome. A sound explanation is provided as to how lap sealant compromises your ability to inspect and assess what is really happening under this unnecessary goop and forms a less effective seal than the technique used in this video. Hopefully, you will never want to use lap sealant again after watching this video.
