I saw Consumer report magazine rates Kilz highly on the 3rd spot in an issue in Sept 2004 (I guess).
Therefore, I decided to go with Kilz instead of Behr. Since then, I have painted over 4 large rooms using Kilz, and the results is pleasantly good. I really just need one coat of paint (light-taupe, light-yellow, and cream-light-pink) to cover my walls where there were a few spots of dirt-brown , and dark brown due to metal scratches.
Due to an offer by American Traditions (AT) in summer 2004, I bought 5 gallons of variety of AT interior paints, mainly light colors as well. I recently tried one cream orange on 2 parts of my wall, and I was disappoited that it was sooo dilute. I really need to paint my interior wall twice to get the full color. Also, part of the walls have primer on; AT really needs 2 coat so that the primer will not bleed through. However, by using Kilz, I just need 1 coat. I painted 2 walls in AT, 2 walls in Kilz.
We have no experience when started painting. Cutting corners is a difficult task for us, especially when using AT, I need to cut the corners twice! Kilz really helps!
