Most people think a car wash with spray wax and some shine is "detailing". But regarding your question, you can get certain waxes on decals and trim, mostly pure waxes. Such as:
Poorboy's SSRs
Optimum Polish
Optimum Hyper Compound
Poorboy's PwC blue
Poorboy's PwS
P21S / S100 wax
Wolfgang HGPS
Klasse AIO
Klasse SG
Jeffs Werkstatt AJ
Poorboy's Natty's Blue
My fav.Pinnacle Souveran and a cheaper one which I like to use on all colors Pinnacle Signature Series II.
Don't go to autozone and buy TurtleWax, please!! Nothing against those of you who use it, but spend a little extra time and money to really take care of your truck. Trust me, I get compliments all the time of how clean my truck is cause I do it the right way.
You can order pretty much everything from
We Are Car Care -- Car Wax, Car Polish, Auto Detailing Supplies, Car Buffers & Car Accessories Store Its a pro detailing site, visit autopia.org and you will learn a lot.
If you do get a wax that stains trim..no biggie..I always use blue painters tape(might take 20+ minutes or so to tape off) but when detailing the right way you should always take your time, and trust me, once you do you will be very happy.
Now if some wax gets behind a emblem or trim remove it immediately with a detail brush or paint brush(that you only use for the purpose)and wipe it out. If it gets on the decal or emblem also immediately remove it with a wipe of a clean microfiber towel. If you miss it and come back later and their is a white stain you can always carefully use a pink eraser to remove the stain.
Clay bar your truck, take a whole day(for first time)to wash clay, wax and interior. It took me 3 hours to clay my truck first time(new cars on the lot need this). It makes your paint totally smooth, gets rid of all surface contaminants and allows the wax/sealant to bond better. Giving longer lasting protection and a better overall look to your paint.
If you have any further questions I'll be happy to help.
EDIT: I use a powerwasher, its 3.5 gpm and 1700 PSI. You can use 2500 and be fine. Just use a 40 degree nozzle(usually the white one) and stand a few feet back. You will not peel off the decals unless you are being aggressive. Once you get a power/pressure washer you can buy a foam cannon and you will have tons of fun washing. haha.. Just look up foam canon on youtube. But I always follow up with a proper hand wash- 2 bucket method.
