There are some really popular paints available for many years that you can spray right on rusty metal and make it look real pretty for a while. Most come in red or blue.
Problem is that your most valued asset continues to rot from the inside no matter how much it shines on the outside.
The real fix starts when the grinder hits it, sparks fly, the worst gets cut out and replaced and it can get real ugly. Paint people scream and whine, but people who understand what hard work and sweat can accomplish just look forward to the strong, beautiful product its builders produced.
Trump is a grinder!
That is an outstanding analogy.
