hey,
1-nope i didn't sand them. just a couple coats of touch up paint and then 2 coats of clearcoat
2-i didn't spray them, its a touch up clearcoat so it came with a little brush
3-the emblems i bought came with double sided 3m tape on it
If your putting them on your 02 just heat them your stock emblems up with a hair dryer, and then take a spatula and pry it off. Clean off the area. There will be 2 holes in back of the stock emblem, just take your time and line up the emblem because you pretty much only have 1 chance with the double sided tape
any more ?'s PM me
