KTo reraising too loose?

The size is ok. Can even be $0.14 as we are OOP. Do not fall into min 3betting and giving chances to bb and btn to call you.
As for the hand - I will not call with it so we can make a bluff with it.

it depends on villians opening ranges & tendencies

Normally i am 3betting this as standard vs most people opening wide enough @ 25nl but we need to consider if someone is only opening like 20% or something or going to call alot and not fold to cbets then it's probably going to be tough to play this OOP

We're talkig about a villain that folds much to 3 bet. Then it is ok.

I don´t like 3bet KTo SB vs BTN. I think we should prefer cards with good playability. I would 3bet here with a read that villain folds vs 3bet to much then it´s good that we have a blocker against KK, AK so 3bet will be profitable.

I think that is the case... If not- fold is better.

I don´t see anything in the notes about too much folding vs 3bet

Also about bet 0,08 vs 0,12. No you shouldn´t bet 0,08 here. Even 0,12 is quite small sizing. I would give at least 0,14. You want to have some fold equity. Also the deeper you are the bigger sizing you should use in theory - on NL2 it´s probably not so important.

Not in the notes. I said that if villain folds too much to 3 bet we can 3 bet this hand.:)
