Could have given this a 10 if possible
Would RecommendWas refurbishing rusted shelving and toolboxes, bought this primer on friend's recommendation. Where has this been all my painting life?!? Wired-brushed and sanded to remove much deep flaking rust before using primer, though not all of the rust. Goes on evenly, dries quickly leaving a bonded matte surface that fills in and hides minor imperfections. Excellent prep for finish coats.
