I read that when your blocking your primer you can near the end spray some gloss black paint since gloss black shows EVERYTHING. My question is does this sound like a good idea, and what kind of black paint could I use that would sand off easy cause I wouldn't want to leave black paint on if i'm putting a silver or white base coat right?

I believe what you are referring to is a 'guide coat'. After you prime something, you add a very light coat of this over the area. When you a blocking, any low areas or deep scratches will remain black.
You should remove all the black before painting. Since your coat is a very light one, it sands off very easily
We just normally use a 99 cent of flat black that you can get at your local Home Depot or Lowes.

No I know what a guide coat is. The article I read said you can spray like one coat of a black gloss paint to show anything you may have missed since gloss black is notorious for showing flaws. Sounds like a good idea but i'm wondering about getting it all off afterwards or if you can just DA sand it and shoot another coat of epoxy primer and/or sealer after that and be good to go.
You can use wax and grease remover...
Spraying paint on a blocked primer is ridiculous...what do you do with the black paint afterwards?
If your primer is dark you can spray a little wax and grease remover on it...or water will do, just to give it a gloss...then wipe it off...
PPG's DX330 or an equivalent solvant will gloss it up long enough for you to eyeball the surface...
Are you using long blocks?

I don't understand the sense in it. That's a lot of extra materials and labor involved to really do nothing. Everything should be straight anyway if the guide coat is used properly
