Re-painting with same color....process opinions?

In about 2 months, I am going to repaint my 71 Dart with the same Poly Gold. When I purchased, I thought the paint was original as I only saw pictures and it was 2000 miles away, stupid me for not asking! Once I picked it up, it was a repaint of the original color and is as wavy as the sea. I am embarressed enough by it to not even take it to a show, guess I am a little picky.

I am thinking to sand all down to bare metal with a geared DA as suggested in the sticky, fill and knock out low spots and block sand the holy snikees out of it to get strait.

Whatcha think?

I am not doing a rotisere, but will be pulling all the trim and bumpers.

Thanks.........!!
