+1 i too work on my own vehicles, i don't always ware gloves, but i do think about what i was doing before hand.This is my biggest fear! spend time everyday around firearms and working on cars so have to plan any work in or around the tank and try and get it done beforehand which isnt always possible!
Definitely worth it i think to atleast have a set of gloves, going to try and make it a practice to wear them normally.
you can see the effect hand oils etc has setting off a skimmer.
