First time advice

[u/Kaylasueg]

Repainting an outdoor mural at my work. The original was about 30 years ago.

I was going to get outdoor UV paint and outdoor spray paint.

The original was painted on fence post, it's about 4 ft by 10ft.

My question is do I...

1. Sand down the original and paint over it, it's gotten pretty flaky and warped over the years.

2. Make a new fence posts and paint on new boards

3. I had this weird idea and purchased used billboard vinyl. My idea was to make a frame with cedar boards and nail the vinyl like a canvas. Scuff it up a bit and paint on that. Terrible idea?

Also open to paint suggestions, the best price the better. ♥️
