Shawano Lake huh, if our house in Cecil doesnt sell this year I might see you out there some weekend. Post some pics when you get her done so I can keep an eye out for you. As far as aluminum polish and sealer goes you might try some of the stuff truckers use on aluminum to keep it shiny, I used some stuff called Metal Gloss Polish and Metal Gloss Sealer for the shiny stuff on a Peterbilt that held up well, but I haven't seen it anymore locally. Raw aluminum looks nice when shiny but it is a job keeping it that way. There was a product called something like One-Coat that you brush on thin that was made to seal raw aluminum after polishing also.
