What leaded(with Pb) solder brand is good ?
- I had 2pcs "lead free" solder one was Stannol and other "Mercury"-brand UK and they would not even stick copper. Lead free is really bad.
I bought already *Panasonic FR*-capacitors from UK ebay seller.
Now I need someone to replace the caps.
So close but so far away in replacing. 😢
I've never seen a hobbyist or repair tech who prefers lead free solder. For PCB soldering I find it easier to use a thinner gauge, somewhere around 0.5mm will make it melt quicker and easier to feed without overdoing it.
There are many good choices, this is a safe bet with free delivery (EDIT: sorry, I saw you were buying from the UK and thought you were in the UK but I see now you're in Finland)

If all of this is new to you, take your time, do your research. There are loads of good videos on Youtube but I like the detail this guy goes into and he knows what he's talking about. He shows a good technique, coming in from the side although I like to drag the iron up along the lead when pulling away to make sure the result is neat even if I used slightly too much solder.

A clean, correct size, correct temperature solder tip is essential for a good solder joint. A ball of brass wool in a heavy cup is cheap and very effective to keep your tip clean while working. When finished, coat your tip in solder to preserve it from corrosion. (EDIT: also, coat a new tip in solder as it warms up for the first time! It will last much longer if you do this)
If you want some stand-alone flux to de-solder or correct a bad solder joint then the cheapest is not a bad option, pure Rosin / Colophony can be mixed with IPA alcohol (IPA you will also want for many uses including cleaning up the flux).

This guy shows you what it's all about, he has other good electronics tutorial videos too.

For Solder irons, if you're just doing a bit of simple capacitor / through-hole replacement and baulk at the cost of a high quality Weller solder station then Antex XS25 are good quality, UK made, basic solder "wands". All the bits you need can be bought from CPC, Antex sell kits which include good enough multimeters and cutting tools.
Further edit: A desoldering pump isn't totally essential but they're cheap and will help you get a good result.
Another edit: Practice on broken electronics you don't care about before moving onto your prized board.
Screw period correct; I wanted a faster system back then. I choose no dropped frames, super fast loading, fully compatible and quiet operation.
