Otay... let's see what we can do 2 clarify dem dare questions...
No... no need to remove all dat chrome from da bumpa... just burnish it well via blasting media. Only nickel undaneath dar dat you don't need to expose anywayz.
Primer... yes to primer for da bumpa... gotta have it when painting over da chrome. Don't matta what kinda paint, you still need da primer.
Wheels... short of hand sanding with wet / dry paper, (600 WET will suffice), using fine media sand @ low pressure so not to induce damage, blasting the rims is the best way to prepare dem fo de paint.
You really don't need to prime the rims... but it won't hurt a thing if you do. You'll just need to sand dem lightly before da paint go on.
*Hint* - pick yousef up a cheap tack cloth at the auto parts store. It will gather any sanding / dust from da rim surface. Use it in conjunction with some compressed air to shoo away loose particles before you shoot, aka gun, spray, hose, (LOL) on da color coat.
- Do not buy compressed air in da can. De last person I seen who was playing wit dat kinda compressed air was sitting on de train tracks. You guessed it... de train came. Bad perception / reaction time. He's riding trains with Jesus now. Dat not real good. Cuz of dumb sh*ts like dat, you now must be 18 years of age to buy dat air. Day will card you at de register and den you will have to run from de po po. Dis is also not good. Member dat!
About dat grill surround... adhesion promoter on plastic is the way to go! Cutting / sanding through the faux chrome is not required. Again, 600 is fine for prep... as would be a scotch brite pad. Not a brillo mind you, a scotch brite sanding pad. Anutha auto parts store purchase, as with the tack cloth. The ZP isn't required, HOWEVA, I would use it if you were able to see sand scratches through the adhesion promoter.
General rule... if you can see it in your final primer coat, you will see it through the color coat. <--- Dis is no damn good.
About color matching that ARB front bumper - no need take it down to bare metal. You would only have to prime the areas you cut, aka sand, through. Otherwise, no primer would be needed as long as you don't break the factory finish.
*TIP* - paint and powdercoat will be thinnest on the edges of a panel. Tread lightly there when sanding so you don't break through.
I would be comfortable scotch brite padding that ARB, den air, den tack, and apply the color. I would go one step further tho, and add a urethane clear coat, (x2 or 3) to the ARB bumper, simply becuz it's face it right up front, catching all the road skully glory! Urethane is hard as a wedding, well, you know.
Hey, holla back ifin' I missed sumpin yo? Peace out! (LOL)

The way I'm hearing you is that I don't need to get all the chrome off with the blasting, just give it a "tooth" right? It sounds like you are suggesting using a Zinc Phosphate primer on the wheels as well or just the bumper? I thought the Rustoleum and VHT paint you suggested don't require primer, will using the ZP mess up their adhesion or would it be extra insurance?
I absolutely loath
chrome so I've got no worries about going back to stock and I'm dropping some serious coin on other parts for the truck so an aftermarket bumper isn't really in the picture. Thanks for the 1.5 cents though.
Since I've go an ex pro on the line here, I'm planning on doing my chrome grill surround as well. I was planning on roughing it up with some sandpaper (not all the way to the plastic) then hitting it with some adhesion promoter and the base and clear I got from automotivetouchup.com. Would you suggest getting it all the way down to the plastic instead? (I don't think sandblasting chrome covered plastic is a good idea right?) I've also heard adhesion promoter is the way to go on plastic/fake chrome. Is that correct, or would you use the ZP on it instead?
Oh one more thing. I'm considering an ARB front bumper as well and I would want it to match the wheels/rear bumper. Could I just prep sand the powder coat and shoot it with whatever I end up deciding on or would it be better to take it down to bare metal and prime with ZP?
Sorry if all of this is a little off topic.
