KILZ Restoration Maximum Stain and Odor Blocking Interior Latex Primer, White, 1-Gallon

I had bad water stains from storm damage here in Florida. On top of that was 20 years of smoking by the occupant built up on the ceiling and walls. I had my doubts but after the first coat it could barely be seen. After a light second coat everything was gone and the ceiling and walls were snow white. I put my colored finish coats on the walls and it looks great. The Kilz Restoration primer sealed in the damage, smoke stains, and odors. There is no bleeding thru on the ceilings which I left white. I'm a regular person and I wouldn't steer anyone wrong and certainly not for a company I have nothing to do with. But I do give credit where credit is due, this primer is great.
