October 27, 2021 - Hi All. I ran across this new product SEMCO Liquid Membrane (SEMCO Liquid Membrane™). I completed some research about the manufacturer and it looks like they've been doing some pretty high profile projects internationally. Saw on their website that customers have used it before on RV roofs and it looks fairly easy to apply.
