RE: Tools: What do you recommend?
My personal recommendation for a heat gun is to get a butane torch instead.
Strings shrink instantly and are easily removed afterwards. I used a heat gun before and had issues with it melting and deforming my prints because you need to keep it pointed at the print longer to get rid of strings.

I agree with @michael-fortin
A handy device would be for example this one:

For just melting of some small artefacts, the heat gun is efficient enough. I would recommend a battery powered heat gun like this one:

For smoothing a surface, you will probably need a gas torch, as the heat gun can not supply the heat fast enough. As mentioned a kitchen gas torch works fine and has dual use 😉
