Use good quality solder and remove it with

it will look like hot-air-leveling.
Hmm, I hadn't thought of that. I know I've tried in the past on junk boards, and
never was able to get the solder smooth and level enough to make it the same as the
surrounding fingers. I usually don't use solder braid, so I didn't think of that.
I'll have to try it when I get a chance, but I still would worry that it would make
that connector finger too thick. I'll definitely try using solder braid to remove
solder on a finger, and see if I can get close to the same thickness. Maybe if you were to
mask off the nearby fingers and carefully sand down the solder, you could get it even
thinner? I'd be worried about burrs and bumps in the solder that could damage the
female connector that it mates with.
The previously-mentioned quick wipe with a cloth or sponge may leave a thinner
and smoother surface than using solder braid.
Secure the PCB so it doesn't move, soldering iron in one hand, cloth/sponge
poised next to the area to be wiped in the other hand. Dry cotton cloth or
warm, lightly damp cloth or sponge.
