Pricey, but good!
Would RecommendWe used this primer in a house that was previously smoked in and previous owners had many pets. This primer sealed/ helped eliminate the odor, but allowed the final paint to adhere really well. While pricey, I would still recommend.

Hides discolorations as expected
Would RecommendI used this in a living room with dark markings on the ceiling due to cold trusses. It went on easily and did the job. I did a second coat with regular ceiling paint, as regular ceiling paint is much cheaper, and it looks like it did the job.

Would RecommendThis primer worked really well covering up wood knots an yellow colors.

Primer hardened
Would Not RecommendThis primer was either old or exposed to air. There was a 2.5" layer of hardened primer at the top of the 5-gallon bucket. The remaining primer was so thick, it couldn't be poured out of the can. The only way to get a 5-gallon bucket is to order online - so you never know what you are getting. That's just poor practice.

Worth driving out of state if you can't buy within
Would RecommendIn my opinion, for exterior pressure treated wood, an oil base primer is the best way to go vs. latex, or water based. Too bad NY state won't allow the sale of the product - was well worth the 2 hour drive (one way) to purchase two gallons and used every drop on an exterior PT fence that had aged one year. With a semi-gloss top coat, looks like something out of Better Homes and Gardens. Also, top coat latex with this oil base primer took less than a gallon, all done by hand with roller and brush...
