recommendations for pressure treated deck sealer please

[ArlyA]

No chemical is perfect but I do like the oil based, UV protecion, semi-transparent stains in general. Must put on when dry of course...

I looked into Aluminum. No one around here has installed it.

That seems to be the same here. I've a good neighbor that was in the deck business and told me it never caught on here. Yet people were paying almost the same cost per sq ft for the "fake" PT, (like Trex.) as aluminum cost for the horizontal material.
Never needs sealing or painting, and the way sealing/paint prices are going it cost almost as much to redo my 40yr old deck every several years as the wood cost in the first place, plus the labor.

I've been using Thompsons clear for a while and it works well; much better than the Thompsons in the red and white can. Darkens the wood quite a bit, giving it an aged look.
