Sand and Bondo my 5x5 Century truck bed lid

Has any one used a power sander for their projects? Or is to tough it out and hand sand the entire lid the way to go? Got mine for free and in bad shape. Perfect project ready. Just want to know what’s better in the beginning to finish and ready for paint.

 

The only time I’ve known of people to do body work and sanding prep for paint they use a DA/orbital polisher with auto sand paper.

While I bet you could go to town with a regular sander you are much more likely to leave a surface not ideal for a good looking paint job at the end.
Its going to be rough and you may unevenly sand the finish.
Its almost like the difference between a rotary polisher and a DA polisher. A rotary polisher builds up a lot more heat and direct power so your much more likely to blow through your paint job.
A DA polisher disperses heat and power to help evenly buff a surface.
