Hi Tank family,
Thank you for your kind words. Our Caravel started out pretty rough and still has it's battle scars. Yours will come along, too.
The polish job was quick and cheap. I used Mothers Aluminum Polish from the local Autozone store and some thin towels from the dollar store. You could be done in two weekends if you do it all yourself. It gives a near mirror finish. The Nuvite and cyclo method gives a blinding mirror finish which is nice but too much trouble for me. You can pick up with nuvite after the Mothers polish if you want more shine but I bet you will be more than happy with the Mothers polish.
I've done several things to our trailer that are not typical. But always with the rule that the non-typical can be put back to original without too much trouble. If you would like to look at my picture log it is at
