Latest pic of the 2013 Black BRZ I did a few days ago
 

This is the 2013 Subaru BRZ that I did a full stage 4 including sealant a few days ago and sponsering for upcoming car shows. This sweet BRZ was just detailed a few days ago and the Reflection is still ultra deep. This sweet ride belongs to a members BRZ's here on the forum in the Tacoma area.

Here is a video I made for this detail just a few days ago. Btw its not showing on mobile phones for some reason and Im still trying to figure that out since Im still learning this software from Sony.

Pic didn't really do it justice, but the video did.

is that just a film or is it a more permanent coating?

The sealant is Nanoskin Shield and it made too bond with the Nanoskin Hydrophobic wax.

does it work well on other colors? mine for example is SWP

I have used it the brz black and my silver rdx...it's amazing...nothing sticks too this sealant...nothing. after about 48 hrs it will actually give a deeper and richer reflection

Think I might have to try this stuff out for myself on my WRB BRZ, I already love RainX, and I've been looking for a good coat of wax for the car as well.

Is that @Luke.Cariveau 's BRZ?

Yes that is Lukes BRZ...
