Pull you tails off
Wet sand (i think i used 1,000)
let them air dry
spray one very fine coat
wait 30-45 mins
another light coat
30-45 mins again
third coat i laid a little heavier, waited 2 hrs til completely tack-free
install
its really basic, i'm certainly not an expert but they came out pretty good
plus niteshades can easily be removed if you fk up too bad
P.S. when wet sanding don't sand the reverse lights
like i said im not a pro, and often make mistakes
