Bobbie,
As a 5'2" vertically challenged woman, I had wondered the same when I scrubbed and polished my trailer 3 weeks ago.
My husband has a "little giant" ladder. I was able to adjust the ladder to the correct height, climb and straddle the ladder with 1 leg on each side leaning over and doing 1 half of the top at a time. Took 2 days to wash and polish (I used NuFinish...didn't work) and now 3 weeks later all my efforts were to no avail because the little bit of shine I did have is now gone. I KNEW I should have just polished it right the first time with Poli-glow!!
Maybe in the
fall when the weather cools and we get ready to put her away for the winter...then she'll be like new when she emerges in the
fall.
Good luck!
