In the French language, I'm searching for a natural way to say,
- There's no harm in applying a little coat of paint, though.
My intention in saying or writing this is to express that someone has a magnificent house but there are some spots here and there where the paints are peeling and I think a little paint job might be needed. I don't want to make it a pushy advice. I just want to make it a milder recommendation. I don't know how I can get across this softer meaning without becoming too pushy.
