Stop in for a cup of coffee

Need to put a little rubber grommet on the top of the hood pop up spring. Seems the top of the spring is scuffing the bottom of the hood where they meet when I put the hood down. Never had this problem before.
I can get something to leave on and then pop off when I'm showing the car. Seen others do it just never paid attention to what they did.
Looks like a trip to the hardware store.
