Grit question
 
I have recently stripped, 100 year old bare wood on the outside of my house that needs to be sanded before I prime it with Sherwin Williams oil primer, and then paint it with Sherwin Williams Duration.

What is the lowest grit sandpaper I can use and still end up with a smooth finish after it is primed and painted?

I am going to do some test patches, but I figured I'd ask what you guys think.

Could depend on what paint/primer product you are using, at what condition/type of the wood, but in general 60/80 grit

frit question Duration Paint?
 
I have no personal experience but yesterday I read a few horror stories about the current formulation of SW Duration paint. It was pretty bad, mold, fading, color changing, peeling, etc. Suggest you do your research before using that paint. Google it, best of luck

Yes, well...we try and keep things real on this site, and try not to perpetuate un-verified internet rumors of that sort

The top coat product mentioned is one of the better ones on the market
I know of no professionals, nor have a heard of any, running into any excessive issues with the product

60 or 80 is fine and you are won't be sorry by using oil primer. I have used Sherwin Williams a few times here and there, mostly thier A100 series, and they make a really good paint.
