You folks that have been around Airstreams for a while will laugh at this, but for this new owner, I was recently amazed with Walbernize.
We have been blessed with our Pete since early November 2013, so he's been getting dirty oh, 6 or 7 months. We have had an exceptionally pollen-heavy spring here (not over yet) and that coupled with camping for 40 nights or so including 2 very dusty antique tractor shows, Pete was a bit dull looking. And he even lives in a pole barn when he's not camping...........
So I carefully washed Pete with car wash soap and a soft brush, and then the real "work" began. I picked up a bottle of Walbernize at the dealer the other day, thinking I'll go Old School this time. I know there are more modern polishes and such, but let me tell you, Walbernize sure impressed me. I know, it may only last 6 months, and so-on. But, compared to the last 6 years of attempting to wax a 40' motorhome this was so much easier. I literally used to spend a week waxing, but Walbernize was SO easy; seriously, wipe on, wipe off, done in about 4 hours.
I did two coats on all the siding, and it also worked great on the rims, rear bumper, pretty much everything. I put WD40 on the segment protectors and everything else that is cast aluminum. Now if I could just hermetically seal Pete until we go again in a few weeks!
