Priming Blistering Paint

got some door jambs with a lot of peeling paint on them that we sanded here. And I'm putting some primer on these also. Anywhere where there's any blistering in the sighting, we're actually using our primer, peel bond primer to actually prime the blistering so it'll stop and seal the blistering. So, got this side of the house. It's got a lot of blistering on it.
