One easy tip I have is to keep windex close by. The alcohol percentage is not enough to degrade the silicon and it prevents the silicone from sticking to your finger, gloved or not, or whatever device you use to apply your sealant. If sealant gets somewhere you don’t want it to be you can use a paper towel/rag with windex and wipe it right up without spreading it.
Cool, I need to try that. Maybe next time I use silicone I won't end up with a sticky mess.
In fact you can get away with just water, wet a paper towel or dip your finger in water.
It was a greasy trick I learned at work to use spit on your finger to form silicone and not make a mess
