I would scrape to get rid of any paint flakes/loose paint and spray either with a heavy duty spray paint or with a paint sprayer. Consider a higher sheen because it’s more durable and water resistant. (Think exterior semi-gloss or satin paint). If it’s from the 60s you might look online to see if you should paint it a different color— maybe something vibrant? And finding cool cushions would be good, but you may have to customize or hire someone to make custom cushions. It’s going to look awesome! And if it’s your first flip, remember that no one will look more closely than you. No matter what you do it will look better :) good luck!
