I used this on the top shell when i had it off one time and it worked well. Then i had to send the P2 into DJI, so i peeled it right off. It works perfect for people that want to change up the color alot. If you live in the US i have noticed that Pepboys, at least near me, carries a plethora of colors.
Nope, 10-12 sats on a nice day.
I didn't check if there's any metals in it, although its basically rubber and thinner.
Doesn't stain the white shell either.
