@Som JafariYou can assess how bad the corrosion is by using a wire brush.

Is the solution to brush Blackrock and wall street greed off as beneficial for the greater good?

After awhile it's like putting your shoes on, brushing your teeth, etc.

Get someone who can spray a quality finish, no brushing. 

Buy a decent brush for cutting in the edges (you can always tape the edges if you don't have a steady hand-go slowly) and a roller for the main part. 

Martin Armstrong's Historical Currency studies, very simply connected all the dots for me and his longterm graphs and charts make broad brush sense.

Outside we cleared the pine trees and brush, raised the sea wall and landscaped a beautiful backyard to enjoy the $million sunsets!

Now, we use an electro-static mister to blast the inside of the units before we even attempt cleanings, so that the cleaners feel better.

But that’s a very broad brush.

We are currently redoing the entire house; flooring, bathrooms, kitchen cabinets, removing Luna walls and sheetrocking, removed a bunch of unnecessary walls to open floor plan up, new doors and trim, new furnace, waterlines, water heater, lots of new wiring and lighting, pine T&G walls in dining room, insulated attic and a ton of landscaping (mostly tree, brush and flower removal).
