After posting the pictures of the first round of primer online, I was receiving a lot of compliments on how flawless it looked. However, we builders know how far that is from the truth. As you can see in the pics, everything that isn't black was a flaw or high spot. Incredible what block sanding can reveal. Todays job was to locate and spot fill the last of the low spots, contour them down and spray another 3 coats of black primer. And this I did indeed.
