start of body work

exactly!

things i should add:

dont spray high build directly on bare metal unless its an acid etch primer like the PPG NCP primer. it will lift AFTER its color sanded, buffed, and delivered...

strip and blast bad rust spots, acid wash the rest and then 60/80 DA and then one wet coat of black epoxy prime.let the epoxy tack off for an hr (70* with 10% humidity) anything with colder temps or higher humidity and it will take longer.

rough out your first mud coat and 80,then spray your high build right over the top of it. after than long block the primer till you just see the black of the epoxy. stop and work any obvious lows, level and reprime.

should take you two primes before you no longer need mud work. then you can 80 long block and prime three times.

It depends on the poly primer. Evercoat suggests not doing it over anything, other than fresh sanded metal, while other brands that I've used require acid etch.

80 + poly primer and a long board + final prime (epoxy or urethane) and it's nice.

I've been experimenting with hand sanding my final color sanding vs orbital/ trizact and I'm going to try it on a bigger panel with an 8" durablock. The orbital sanding looks great, like what you've got showing in your pic, but the hand cut areas that I've been experimenting with so far are as straight as a laser.

I've also found that it makes all the difference when you spend more time with the wool pad, before moving up to finer compounds and foam pads.
