A request for ramblin robert

Eastwoods rust encapsulator.
It's been on there for 3 + years now, looks like the day I brushed it on.
I have been told it is "no good" and or "it's the same as bridge paint".
I also have been told the red is better than the black as the red is the original formula.
I sprayed a section with some spraybomb sating black and it still looks like the day I did it to.
Car has been sitting outside with a tarp on it for most of the last 3 years. I had some medical trials and tribulations. I think I will actually get back to work on it sometime this winter....
Anyway, the encasulator brushes on and once it is on, it seems to stay there! Doesn't need any special prep to paint over either. You can by spray cans, but for the kind of work pictured brushing on seems to get better coverage. no overpsray.
