I work for Blue Beacon (building and maintaining facilities) and wash my Cyclone several times a month. I ask for the straight wash (no brightener) and I have Rain X applied once a month. After driving in bug season they will need to brush the front cap to remove bug debris fully. My rig still looks like new with no isssues in regard to the stickers peeling off.
The bay attendants are well trained in regard to washing RVs and are aware of keeping high pressure wands away from surfaces that may be damaged (speakers, awnings, ect.). If you have any concerns at all please tell the supervisor (the person that guides you in) and they will help you. If you have stickers that are peeling or cracked point these out prior to your wash as the pressure will take off anything not well secured and they will "stay off" of those areas.
If it sounds like I am "tooting" Blue Beacons horn, I am. I have been working for this family owned company for 18 years. They have built the business based on customer service as job #1, if you are not happy with the wash, tell them about it, they will fix it for you. They know you have spent a lot of money on your RV, you are spending money to maintain it, and they are happy you chose them to care for you rig. That is the reason Blue Beacon has remained successful through these tough economic times, and continues to grow.
