I’m looking for some advice with restoring an older finish.

I have a 1960Buick that has spent the last 35 years in a barn. (Uncovered). The car looks to have beenpainted in the mid 70’s and looks to have enamel paint. The paint is Red and oxidized.It also has numerous surface scratches and stains from years of sitting in a barn.

I’m assuming a deep buff with a heavy compound followed byswirl remover or finishing polish. What would be the recommended compounds, pads and tools? Would it help to provide a preliminary sand with high grit paper?

I'm not looking at a show car finish. Just want to bring some life back to this old girl.

Thanks!
