After reading the www.airstreamguy.com
website on his recommendation on polishing... it wanted to try it. So I went to Lowes and after a couple of attempts and misdirection form the sales associates... I found Diamond Brite Truckbox Polish and the bottles were dusty and everything.
At $13.50ish a 8oz bottle I bought two and proceded to try it and was happy to the results. I also notice if you apply it a bit more liberally, it speeds up the process noticably... and I strive to be a smart and lazy person.
So after some searches on the web... I found the distributor and pricing for a gallon at roughly $100 with a $15 shipping/handling charge.

At a overall price of $7.25ish a bottle... I'm not worried about being skimpy with the polish which this speeded up the polishing dramatically.
Just thought I'd share.
