Yes it is Simoniz, yes, it comes in silver (that's the product number above).
No paint is 100% petrol proof/ chemical resistant, unless you go for a 2K. But, on my engines where a little petrol has touched the paint, as long as i wipe it off, it doesn't take the paint off.
Difficult to find anyone who can use 2K without getting lots of dribbles when trying to paint in between the fins.
