I rattle can-ed my Nighthawk (below) with Dupli-Color Honda Nighthawk Black Pearl and Dupli-Color Clear. I can tell you the Dupli-Color Clear will not stand up to gas spills on the tank- I read this and have been very careful to not spill any. There is a 2 part rattle can clear available but I forgot the name of it, I plan on using it in the future. I'm not sure if you need clear for matte finishes so this may be TMI.
The headlight housing being chrome with be TOUGH to cover correctly and have it match the rest of the bike's color.
turn light housings should be the same as what I did with my fairings, sand them smooth, make sure no debris is left, and prime, sand, prime, wet sand, paint, wet sand, clear (or matte, not sure of the process).
The tail light housing and gauges are chromed plastic. I've never painted this, but have heard it's tough but not nearly as tough as the true chrome headlight housing. Try the self etching primer or adhesion promoter as suggested.
HOWEVER- if your gauge housings are in perfect shape without scratches, I'd gladly trade you my scratched up housings for them. I'll even do the prep work on them for you!
Your tank and fenders are metal, so you could do what I did for my Nighthawk tank (the fairings and rear cowl are all plastic). What I did for my Nighthawk tank (I'll leave out the dent repair and bondo I did) was I stripped all the paint off the tank to bare metal (do not do this on plastic pieces as the stripper will melt the plastic) and sanded in varying grits starting about 800 up to 2000. I then used alcohol to remove all the dust and let air dry then immediately put self sealing primer on it. I then sanded that using the same process and finally wet sanded with 2000 or higher grit. Let dry. Again, apply alcohol to clear the dust etc, and I then put the black pearl color on. I had a hard time sweeping the can too fast because I didn't want to lay the paint on thick, and I was accidentally "fogging" the paint so I had to slow down my sweeping motion. Once I corrected this, and had a nice even finish, I wet sanded with 2000 again, alcohol-ed, let dry, and then cleared waiting about 10 mins or so between coats. I ended up with a great finish and get compliments on it all the time. Not trying to brag, but no one believes it's my first paint job.
If there's one thing I read that one should take to heart, it's PREP, PREP, PREP. You can never prep too much. If you see the slightest imperfection at the primer stage, sand it off. You get the smooth as glass look from the prep at the primer stage, not in the paint or clear. I worked in my garage without a booth downdraft so I was constantly worried about contaminents. And don't paint when windy outside.
PM me some of those links to doing a matte finish. I'm putting together paint ideas for my vulcan and shadow and would love to know how to matte paint correctly since it's all the rage. I'm thinking about doing my tank and fenders half matte, half gloss in this certain striping/flaming effect. If not I'll probably go all gloss with the effect/stripe done in a dark gunmetal on top of black.
One last thing, DO NOT use Rustoleum primer, because I read there is something in the rust proofing there that reacts something terrible with the paint (unless you use Rustoleum paint). General rule that I read is use the same manufacturer of primer and clear as you will for the paint color, that way everything is guaranteed to be compatible.
