The skin of my finger tips is in poor condition and my skin breaks open like really deep paper cuts along the lines of my fingerprints occasionally so I was planning to use band-aids while playing if I do find myself with an instrument in my hands. But it has also been on my to-do list to see if there are there other ways to protect the finger skin. I didn’t even think about liquid band-aids. Good thinking.
I just googled “finger protection string instruments” and found many products to try.
