Try soldering an SMD capacitor onto a scrap circuit board. First try gluing and soldering, then just solder a piece on and the rest with hot air. I think that it works best with hot air because with the soldering iron you always move or pull the component away if you don't hold it firmly in position. I actually prefer to solder components with a soldering iron because this way neighboring parts on the circuit board heat up much less. I use UV-curable solder mask varnish to glue things on. I've noticed that it's relatively easy to remove again, but it doesn't work well that way because the component comes off too quickly as soon as it's heated with the soldering iron. If it doesn't come off, then it would be an idea to get the component in a better position. With the soldering iron you unfortunately always pull or push the component a little so that hand soldering is impossible without holding the component. I don't want to use any other very strong varnish or adhesive because I like the fact that you can desolder the component again without too much effort.
