@raingarden you can paint over it with no bleed through. It cures solid.
@gtaus I'm also wondering about the heat effects here. South and north side has good shade, west side (hottest) is unpainted and has a 10x14 covered run in front of it. This side faces East so hoping to skip painting it...but guessing I'll have to.
This is what I used:

It is used to coat the inside of planters to extend their life but don't believe it's non-toxic. For paint on waterproofing there's also rubberized roofing. Again, no idea on toxicity. Lots of houses have flat roofs here and there's a wide range of products for coating them to keep them from leaking. The asphalt however also helps preserve wood.
Hoping to make it last as well as plywood. Not sure that's doable, but this is my try at it. This osb was beautiful when I bought it over the summer, but I was still in a cast boot at the time. I had it stacked and covered with a tarp. Rain leaked through and caused some damage. Hoping this mitigates that.
