RV wax is made to do just what car wax does.
It protects the siding and keeps the finish sealed. The sun's ultraviolet rays are hard on an RV's exterior, so it needs to be protected.
The sun will fade out your paint or stripes without some kind of protective seal over it.
The front of your camper catches the wind, rocks, rain and general road grime.
Be sure to really coat that for extra protection. Also be sure to get some on and under the gutters.
The sun's damaging rays seem to be attracted to rubber parts and they will soon become brittle and break.
An RV cleaner with wax is much cheaper than replacing all those pieces that need sun protection on them.
There are several brands of cleaners, like Camco, which has a whole line of cleaners for all the various materials and finishes on most RVs and campers.
Other companies include Gel Gloss and B.E.S.T.
I've been hearing very good reports on Meguiars 50 but have not tried it myself.
I would be very interested in hearing tips from readers about what you've tried that worked or didn't work.
An RV gel cleaner is a great product for the upkeep of your RV. It is 2-in-1, so you save money.
It makes waxing your RV easy and fast. Just spray and wipe!
This is the way to wash and wax at the same time.
Waxing your RV by hand takes a lot of time and effort, so make it count with a quality product.
Apply it liberally.
Be sure to wipe it off completely.
It will leave a haze on your camper walls if you don't.
Leaving it on for days will not protect it any more than letting it dry for a few minutes and wiping it right off.
