1: do you really need to seal the cut end grain of pressure treated lumber (for deck framing...)?

2: if so; is there a product that lets you dip/slather it on and immediately install the joists into the hangers?

Yes I would want it sealed and to the #2 question, that is what we did.

But they didn't call it a sealer then so maybe it is thicker now.

Either way just a 2" roller and a brush, it does not take much in time. You don't wait for drying.

Around here they are never sealed.c although there is no downside to doing so.

Copper napthenate. Often called 'End-cut wood preservative'. Last I bought was made by ArmourAll and came in a 1 gal paint can.

FWIW, its a preservative, not a sealer. I re-treat my whole deck every 3 years or so. Stinks for a while, but that passes.

You should. Coppercote or Anchorseal2. Does everyone do it? No.

I do it every time I have to use pressure treated wood. It is cheap insurance. Paint it on and forget it. I try to not use pressure treated wood if I can at all help it. For anything that can be touched by a human on a consistent basis, like a deck, or fence, I use other types of wood like IPE, Mahogany, Cedar, Teak, etc..... Pressure treated wood is injected with a chemical acid that is not good for humans to touch, and never use it around anything that will touch food or plants.

I got a spray bottle of stuff off Amazon so I didn't need to mess with painting. Also only did it on thicker stuff. I could sort of see which ones didn't get penetration all the way to the center. No idea if it made a difference but was cheap and easy

What was the spray stuff?

Someone told me to use the rubberized undercoating you can get anywhere including auto stores. So I did that and it seems to work well thus far- my raised garden hasn't warped much, so I'm not sure if that is the test of effectiveness
