Well I guess it all comes down to what the definition of "invisible" is (and I'll not ask Bill Clinton..).

Most of my work is surface mount work, and other than the area of rework looking cleaner than the rest, my work is nearly imperceptible, but not on purpose.

I use a lot of flux installing a flat pack IC to insure excellent solder flow out and I always clean the area thoroughly with a fiber brush and acetone. Yes, the cleaning makes the repair mostly invisible but it allows me to eye-loupe the repair looking for any solder bridges, unsoldered connections, or questionable connections, and it takes seconds to accomplish.
