Wash, wax and treat

Cooling off while camping at the beach is a treat that is followed by our annual big wash and wax job. We have learned the importance of washing off salt deposits to prevent or control corrosion. We will probably limit our beach-side camping to once a year, not only to limit the exposure of salt to our trailer, but also to cope with the reality of mandatory water rationing that is about to begin due to California’s third year of drought conditions.

Notice that I’m using an extended scrub brush compared to flooding the top of the trailer with our precious fresh water as seen in this photo from last year’s washing.  We are following many of the tips to conserve water seen here.

Before washing the trailer, I needed to tend to a few minor details…

dsc_0060-smashed-marker.jpg On our return home from our last beach outing I successfully negotiated the busy Interstate 5 freeway and was driving up our neighborhood hill. A car was coming down the street so I moved over to the right and, when the car passed, I pulled back toward the center of the street as I accelerated up the hill. I heard a barely audible “boom” which sounded like something had shifted in the truck’s cargo area. An hour after unhitching I noticed a slight dent in the rock guard and a smashed amber marker light. I must have hit one of the large plastic city trash cans that were out that day.

dsc_0069-new-marker-lt.jpg This gave me an opportunity to learn how certain parts for the Airstream are obtained. Airstream, Inc. was helpful in giving me the correct part number (511750, Marker Light, Amber Teardrop) and the two closest Airstream service centers. I chose C & G Trailer Service, an Airstream Certified Service Center that has had an association with Airstream since 1946. They had the part and could ship it via UPS, but we drove 113 miles up the coast to get it so that we could see their service center and become familiar with driving there when our trailer needs servicing (San Diego no longer has an Airstream dealer or service center). I installed the light fixture at home and substituted a flat #6S brass washer and added a #60 rubber O-ring to reduce the incidence of moisture getting into the light. Another LED bulb (67-A15) has been ordered to match our other marker lights which Larry had switched to LED.

I was now ready to wash the trailer and used Meguiar’s Deep Crystal Car Wash (See Meguiar’s over 100 year legacy and family history).  San Diego has hard water and water spots are prominent after washing. I added a cup of vinegar to a bucket of water and used a chamois to remove the water spots. Then I inspected the trailer for filiform corrosion which is showing up in newer Airstream trailers and extensively documented in the Airforums.com thread, “Corrosion problems with new Airstreams“. Last year I treated my filiform corrosion with Boeshield T-9. The label on its 12 ounce spray can indicates that T-9 was developed by The Boeing Co. for lubrication and protection of aircraft components and contains solvents, lubricants and waxes designed for penetration, moisture displacement, lubrication and protection. It dries to a thin, clear waxy film that clings to metal. One year ago I applied T-9 to my filiform and I am glad to report that I saw no expansion of the filiform. Compare the current filiform image below with the one taken last year.

(Whitish circular areas surrounding the rivets are actually incompletely removed waxy residue from Mequiar’s Mirror Glaze sealant.)

The following day was the wax job and, as indicated above, I used Meguiar’s Mirror Glaze Professional Polymer Sealant #20 that can be obtained from a good automotive body shop supply store. (Thank you, 2airishuman of Airforums.com for sharing your wisdom and insights on protecting trailer exteriors.)  I bought the 64 ounce size jug and used it to refill the 16 ounce size squeeze bottle which is easier to handle while on the step ladder. (The roof also gets a protective waxing.) This is my third year using this product and I can report that it is durable and withstands washings throughout the year. I also believe that using the above two products goes a long way in preventing and/or controlling filiform corrosion.

Also note that I observed Sun safety while out in the sun by wearing a broad-brimmed hat, long sleeve white shirt (Columbia Titanium), sun glasses that protect on three sides, and sunscreen.

So by the end of two days the trailer was washed, waxed and treated for this season.

(Larry made the covers for both the Super Jack and the wheels.)

So now it’s time to relax and enjoy summer and our own back yard.

    Great info on exterior maintenance, Bill! Thanks for documenting your experience. Now, if I could just get motivated to clean my Airstream!
