My pro paint store will not stock or sell Kilz products. They are tired of hearing the complaints. Just sayin.'

Personally, I've only had big time problems with the original oil formula. Everything that was used on failed within a few months. It's OK over knots in pine, etc. I don't use the water based stuff either. For the money, there is much better material to be had like Glidden's Gripper.
YMMV
