Extremely hydrophobic!
This stuff is pretty impressive.  It comes in an old school wax can and has a very strong smell thats clearly hazardous to your health so I recomend wearing a mask while applying.  It has that stuff than non stick frying pans used to have so its not great for your health, but holy cow this stuff repeals water like off my paint the same way oppisite magnets push away from eachother!  Sometimes after a light rain there is dirt left on the paint which needs to be rinsed off. Not this stuff, its as if the dirt sticks to the water and rolls right off the paint.  Will update in 10 months for longevity review.  I would also use this in small sections as it can be a little tough to buff out if you let it sit more than a few minutes.
