Can the outside corners of a shed be "Flashed". I'm building a 10x12 shed with Smart Panels but my math was off a little and all the outside corners don't butt together and are about 1/2 inch off each other. I will be installing 4" trims so they will be covered but I'm wondering if some kind of flashing can be used before installing the trim (either metal or the same sticky membrane you use on windows) Thanks

Ok all you expert painters out there I need your help. Most of my house has held up well to paint weathering except for yes of course the southern and western exposures. I live near San francisco and get mixture of sun and fog. 14 years ago due to weathering I re-sided 2 sides of my house with fiber cementsheets. The one sun side has severe chalking and due to a combination of lower quality paint perhaps and too much red pigment in the paint, it has faded to pink and looks aweful. I was able to re-paint the one side, but this side needs scafolding since I am on a steep hill. I have gotten a few quotes to repaint and of course each has a slightly different take on how best to do the job. Due to the chalking both estimates included pressure washing. One quote wanted to prime and then paint with SW Superpaint one coat. I am changing paint color slightly, less red pigment to minimize fading. My question is why prime since it is not bare wood or unpainted factory fiber cement? I used a tinted primer 14 years ago and that is what it is fading to now. Because of the difficult access and scafolding requirements, I want this paint job to last as long as possible. Should I go with tinted primer+ 1 topcoat Superpaint or will I get more mileage with 2 topcoats no primer? or Use Duration one or 2 coats. It will be sprayed and backrolled. I have also been told low sheen should help with reflecting a bit with U-V rays. Thanks in advance for your feedback.
