Well, that's encouraging. wood is wood, prime it paint it. What I liked is there was the mention of photo-degraded wood surfaces, so sanding is more than just the dirt and loose paint stuff.
Anyone know anything about the fuzzy/duff stuff that does come up when sanding cedar? Is it degraded stuff or...?
And, re: sanding: if unprimed cedar has that "new" wood look -- and it weathers to gray over time. Then the gray is suspect degraded and needs to be sanded back to "new". That's basic wood refinishing. My question: given the thin gauge siding in question and the inherent softness, isn't it more likely I'll be sanding all the way through(!)
