[sdiy] To SMT orNot to SMT.. that is my question

We use Techspray 1634-12S no-clean flux remover defluxer.  Seems to work well.
I hate solder pastes - they leave little balls of solder all over the board that risk causing shorts.
The liquid rosin makes plain solder work for me.  People complain about the smell but I lost my sense of smell several years ago....

What are people using for flux and cleanup? I'm using a large MG No Clean Flux Paste syringe and while it solders great it does tend to leave quite a mess. Then I cleanup with good IPA but this tends to leave a sticky residue that takes a long time to dry. Hate that.
