To get sharp clean edges use FINE LINE autobody tape from 3m it the best the roll i bought $7.00 bucks at O'reilly.An scuff with 400 grt sandpaper then wipe clean with alcohol an i wiped everything down with a microfiber cloth,then 5 coats later,DONE!! 
I ALSO MEASURED FROM EACH TAIL LIGHT DOWN ON EACH SIDE TO MAKE SURE I WAS PERFECTLY EVEN ON EACH SIDE AN PUT A LEVEL ON TOP LINE TO BE EXACT AN I MEASURED THE LOWER SIDES SO THEY WERE EXACT ALSO !!!

I was a spraypainter for nearly 30 years. Commercial Jets/Corperate Excecutive Helicopters and Porsche's.
Very nice products to use for this are:
3M Vinyl 123 or
Sherwin Williams Polane (my favorite)
The nicest approach to a textured finish is as follows.
As you saw in this thread the OP used 3M's fineline/endlessline tape. It is VERY GOOD stuff to mask off his area to be painted.
Use a PPG grease and wax remover (or akin to) to remove the contaminates. Always wipe behind the wet cloth with a clean dry one. Repeat this 3-4 times.
Instead of using sand paper, you can achieve deglossing and promote adhesion by using a 3M RED Scotch Brite Pad. This will do the same as the sandpaper and shall conform to the rear vents contours MUCH easier than sand paper.
After scuff sanding wipe it again with the G&W remover, followed by a clean dry cloth.
Then use light pressure on a tack cloth to remove any excess contaminates.
Using gravity feed spray gun is very nice for this application because gravity feed guns produce less overspray, because they require less air. A cup gun for example requires more air to suck it out the cup through to the gun nozzle. Gravity feed, the material just falls into the path of the nozzel, and only subtle air pressure is required to atomize the material/paint.
Sherwin Williams makes a primer for it's Polane (urethane) but any other smaller quantity urethane primer (rattle can) can be used under the topcoat. Urethane primer is very light bodied and needs only a very fine coat. (don't try to bury it)
But once primed, and your color coat is applied using a gravity feed gun (mixed per mfg instructions) and 'hide' is achieved (color is good throughout/even covered)
You then let it try. Sherwin Williams dries to the touch in no time. But let it dry for a few hours to let it tighten up.
Once the color coat is on, you then use the same paint but reduce it only half as much. Hence the viscosity is thicker.
Now you have thicker paint in the gravity feed cup you open the fan pattern up on the spray gun making the pattern a bit wider. Varing the air pressure you can create texture to you liking. In my world professionaly is was textured to a 'grade'. A B C D -D being the most pronouced- A being the finest.
I like your thoughts and curiosity toward texture. It adds a pleasent astetic value, and helps the durability.
PM me if you really want to try this. It is easier than you think, and I don't want you to be intimidated by what I wrote.
Essentually the texture is created by the heavier viscosity material being subtley applied over the topcoat.
The nice thing about Sherwin Williams Polane is depending on the amount of catalyst used, it can render either a flat black finish, or semigloss. Technically you could have semi gloss texture over flat black of visa versa.
Many of the finest aircraft cockpits in the world are finished this way. Or a sprayable suede finish. Beautiful stuff. The suede finish is used to prevent glare off the instrument panel.
Cruise by and Sherwin William paint store and ask about Polane, and ask to see the texture graded sample chips. They may be termed BAC A through E BAC= Boeing Aircraft Commercial
