Wow i never thought i would see this come up in conversation lol, i have done about 20 emblems and they all have come out very nice, the first couple sucked but after 2 or 3 you get used to. this is the way that i have found to be the best and most effective way to to prevent any defects or chipping later on down the road. my recommendations for you is this.
1: removing the emblem, if you have not done this i suggest you do it on a hot day or get a heat gun to heat up the double sided sticky tape on the emblem, this
will make removal a lot easier. you can use either fishing line or dental floss. get enough to get a good grip on and floss it between the car and the emblem to
separate the adhesive. the emblem is also held on by to plastic rivets, so when you go to pull it off make sure you pull evenly on both sides of the emblem so
you don't brake it. get a bottle of goo gone to help get the left over adhesive off the car.
2: before doing anything else, get a bottle of bleach. soak the emblem in bleach for 12-24hrs, after the time is up drain the bleach and use a sponge with the
green side on it to get all the crap off the emblem before soaking it for another 12-24hrs. do this 3-4 times.
-- the purpose for this is the bleach eats the chrome off the emblem so you have just the plastic witch gives the paint something rough to stick to instead of
a smooth surface and you wont have to worry about chips in them or scrubbing to hard with a brush at the car wash.
3: after the chrome is off the emblem then you can use the dremel to get the shape you want, on the back of the emblem you can see little support areas, i
used those as references as to where I am going to cut the emblem.
4: get some 3mm double sided adhesive tape and apply it to the emblem before you paint it. them cut off the excess, do this while leaving the plastic on the
other side of the tape. the reason i do this before paint is so you don't have to worry about cutting into the paint to get rid of excess tape.
5: now you should be ready for paint, be sure to apply light coats keeping the can 7-10 inches away from the emblem always start spraying off the emblem and move across the emblem preventing drips or runs in the paint, i personally suggest sanding the emblem with 220 then apply 1-2 coats of sand-able primer, use this just incase you need
to sand it to get any other imperfections out. then after it dries apply 2-3 coats of what ever paint you want, then if its a gloss paint or flat use 1-2 coats of
gloss or flat clear coat to secure it all in, let sit for 24 hours after the last coat to ensure you don't finger print it.
so you will need
floss or fishing line
goo-gone
bleach
sponge with the green scrubby on one side
220 grit
sand-able primer
paint of your choice (flat or gloss)
clear coat (flat or gloss)
and enjoy.
