Is it financially irresponsible to have my old car repainted?

I have an 09 Civic with 150k miles. It’s in perfect mechanical shape. The clear coat on half the car is peeling and looks bad. Only fix is to repaint half the car. I bought the car used and the other half was repainted before I bought it and is fine.

Would it be a financial mistake to repaint half the car? The car isn’t worth much and the paint job is expensive. I drive this car 100 miles per day for work plus any out of state trips. I love driving the car and will drive it until it dies. Hopefully at 300k miles. Just hate/am embarrassed at the paint.

Edit: it would probably cost 3k to paint

Edit: Just got a quote from Maaco. $1,100 for the whole car, single stage paint. Won’t be perfect but would look a lot better than what I have now.

Edit: I decided not to repaint my car now. Not worth the money. Maybe I’ll reconsider it in the future.
