I was unable to make an edit due to time limitations so....
In case anyone was wondering, I just waxed my 5'er, decals and all, and it looks great. No bubbling on the decals whatsoever as per what some said would happen. I guess those guys at the repair facility know what they're talking about. Just remember to us a good grade wax that would be OK for those expensive plastic boats and cars, i.e. Corvettes. I think I used Meguiar's Yellow Wax though I'm sure there are other waxes available.
OK you trailer/5'er/pop-up and motorhome buffs, get you wax and some clean cloths ready and "go to it".
Ah, the wife will be so proud of you and will be the first to say.... *Now hon. you can wash and wax my car.
