Wow !Fun times!!
My recent "misadventure " doesn't come close to yours. After I finished spraying the clear and letting it set for a few days I cast my eye over the frame and saw a few "starved" spots. So wet sanded and then used a different n&n 1.4. And now am quite happy!
Yesterday morning I sprayed "frame saver" into the interior. Now will wait a bit to build it up.
Time to go back to staining the exterior of our home.
