Well nice weekend coming up, and I am planing on painting my shed. Now two years ago I primed, and put one coat of tan paint on most of the shed. A few weeks ago I primed the gable parts of the shed that had never been painted before. Oh and BTW it is T111 siding. Now all the old paint, and new primer is is great shape. Not dirty, not chalky, not chipping, and not flaking. I should be ok just cleaning and painting right over this old paint right? The siding pretty much sucked up the old paint anyways, so it is not thick at all. Anyother tips for me that I might be missing??
