If you plan on painting the whole piece, the best bet is to strip the chrome off. All you have to do is soak them in some bleack, simple green, brake fluid, or oven cleaner for a while. The chrome will dissolve, leaving nice, clean plastic instead.

Like Gino said, I wound up using spray oven cleaner some time back for my Dodge Deora chrome parts. After a bit, the oven cleaner removed most of the chrome plating and an old toothbrush removed most of the rest. Certain the quickest way I've come across.

Not all types of model chrome comes off with regular household bleach but that is the one I've had the greatest success with. Simply fill a small container with bleach and then dunk the part. For several minutes you'll think that nothing is happening then quite quickly the chrome will completely disappear.
Hope it helps,

Also, solvent based model glues will not adhere to the chrome either. You'll need to carefully scrape the chrome from the area you want to glue. The chrome is a very thin metallic deposit over the parts. It is not as durable as chrome plating found on real cars.
Also, a specific clear coat is applied to the parts prior to plating. This coating evens out the surface of the molded plastic part and also helps the metallic deposition adhere. On occassion the clear coat can cause problems for painting or gluing as well. While bleach will remove the metal it won't remove the clear. Oven cleaner will remove the clear, but is caustic and should be handled with gloves. Yeah, I've tried to be "manly" and wound out with messed up skin in the process. And the fumes can get you as well. Brake fluid, while an effective paint and clear coat stripper, tends to soften or soak into some plastics. My preference for low-buck paint stripping is Castrol Super Clean in the purple container. Again use gloves and always test a piece of sprue to make sure it doesn't ruin that critical part. Finally, if you just want to strip the chrome, not the clear, bleach, glass cleaners containing ammonia, or ammonia will strip the metal only. just do NOT mix bleach and ammonia or you get deadly gases. No, that is NOT one thing I've experienced, nor do I plan to.
