The only thing you will do when you block sand your primer is to make the car straighter. I painted my car black which is the most difficult color to look right and using a high build primer blocked it 5 times in one area just to get it right. This is a step that should be done to make your car look amazing. Do your first block with 150 next at 220 next at 320, 400 up to 600. Depending on how straight the car was to begin with you can skip the first couple of steps. As the car should be 220'd when you do your filler. You bet block sanding primer will only make it more beautiful make sure to use a board that is flat and depending on the size of the panel will determine the size of the board. Do your blocking with diagonal swipes only as back and forth motions will dig into the surface of the primer and make ridges.

Certainly. You may need to sand and "primer" it first to ensure that the new paint color will properly adhere to the metal. This similar method is used to paint cars, too.

Do you have to apply primer to farm tractors before you can paint them?
You should have a paint spray gun that is designed for painting cars and vehicles. You should also buy the proper paint for cars. Green or red are good colors for a farm tractor. If you have rusty areas on the tractor, you will need to sand them off before you paint it.
Automotive flatten paint?
I have never heard that one before. They are either talking about a flat type paint, which is a flat color, with not gloss, like primer almost. Or, the other thing could be talking about primer. When you paint a car with a high dollar paint job, you want a great shine. The best shine comes from a perfectly flat, no ripples, panel. Good luck with that one. When we paint those bubble gum colors on those cars we put about ten, or more coats of primer on the car, and then we block sand it down between every coat. Reason is, when we put on a coat, it adds thickness, or puts another layer on. Then, we take a piece of sand paper, and put it around a block of wood. What this does is remove the primer from the high spots, and leaves it in the low places, thus filling them in, and leveling out the high, and low spots, without having to use filler, or Bondo, which is frowned upon. If you block sand it enough times, that paint will shine like glass. It's all about smooth-ness. The paint has to be smooth, and applied properly, to achieve this, as well.

Can you paint over a latex high gloss paint with latex primer without sanding first?
You didn't mention whether you were using latex or oil based primer and paint, but generally the point of using primer is so that you can paint over it with any form of wall paint. Just read the label on your primer can to make sure it is compatible. On the other hand, if you wanted to paint the primer over the satin gloss, you need to sand the surface lightly to remove the sheen of the paint and provide a suitable surface for the primer to adhere properly.
