The metal panels are looking really good. The louvres were always going to be an awkward job, depending on how soft the aluminium/litho plate is.
With a different covering it might not have been an issue since it didn't start wrinkling until the third coat of dope. I was counting on it shrinking some but I've only used lightweight silkspan in the past. That stuff only takes about three coats to seal but this standard weight stuff takes eight. Getting the tissue wet and letting it dry that many times may be taking it's toll on the weaker areas. I noticed Darrin using Coverlite on his latest DR.I build, which I believe is the same as Litespan, and it looks really good so I'll have to give that a try.
Thanks for the props on the metal panels. That was another step like fabricating the skids. When you haven't done something before, coming up with the method takes longer than actually doing it. Now I've acquired another tool in my technique box. This model is providing a lot of opportunities for that.
