Not sure if this would be the proper section to share, but I posted a blog on my site today in which I share pictures of the corrosive effect treated lumber has on uncoated nails.

Sure, it’s a shameless plug for my blog, but I thought I share in case anyone would like to use the pictures for examples of “why you shouldn’t do this.” I wish I could find the screws that were removed after a year in the same treated lumber–I don’t think a single one came out without breaking. Kicking myself for not taking pictures of that!
