Bullets, eh? Fortunately that's not a problem in my neighborhood. Might try that to protect windshield from rocks.
I'm seeing a bunch of different things marketed as POR 15. Anything from "chassis coat paint" to "top coat" Is there a Real McCoy?
That said, how about grass? Does it simply not stick or does the POR 15 make for better release when spraying? I experimented with cooking sprays on my snow thrower. I'm going to try the POR 15 on my newly purchased ancient Woods mower and a trailer I picked up. Top is immaculate, but the axles need a coat of something.
POR 15 Chassis paint is a furane resin that reacts with water.
It does not generate any gas when it reacts and goes hard so there are no micropores for water to penetrate.
It was developed by the US navy ( AFAIK ) for painting ship hull.
Once fully cured on a properly preparred surface it can not be removed by anything short of a grinding disc.
However nothing is perfect and it is not UV stable so has to be top coated if it is exposed to sunlight,
I use about a gallon of it a year for painting old decks.
Once painted that is the last time it will rust.
I used it on the hire cars that live out in the weather and not a spot of rust in 15 years outdoors.
We also paint the insides of steel rainwater tanks and they never rust either.
Since becoming a mower mechanic I use it on mower decks and particularly on push mowers where the height adjuster locates with a pin through a hole in the base.
No more wear of the holes ( the steel distorts & bends but the holes do not enlarge.
