Cedar siding on my garage needs some attention. It was painted not stained. And from my best estimate painted at least 20 years ago. I'll replace the badly cupped/damaged pieces with new, primed cedar. From the pics, you can see the degree of attention rises along with the height off the driveway. When I did the gables I replaced most of the siding except for 1 or 2 courses well protected by the soffit. Those were just lightly sanded, primed and exterior latex coated. The current effort needs a lot of scraping& sanding. Like the gables I can probably get a way with a light sand and wash for the upper courses. I seem to remember cedar generating alot of "fuzzies". Aside from their annoyance are they bad?/sign of age/needing replacement? From the pics do you think it all should be replaced? Or can cedar be sanded and repainted for (long-term) benefit? What grit (type)? And what's the poop on caulking the butt-ends? I read in another thread that priming the cut ends should be enough. Is caulking a true no-no or more of an aesthetic issue? thanks folks.
