Jared,
Someone posted earlier that a truck stop would do it for $300.00. I'm a bit suspicious of that price or certainly the quality of the job. I spoke with a professional polisher a few years back in St Cloud, Mn. that quoted $25.00 per foot (25ft x $25.00 times both sides = $1,250.00) That is for a polish of the outside toons only, nose cones, and end bells... basically only what shows. That price did not include any application of Sharkhide protectant.
A buddy of mine with S.O.B., had his done by this outfit last spring and spent $1,000.00. The polish job, in his opinion was well below satisfactory. He then contracted with another polisher to both polish and apply Sharkhide. He reportedly paid that guy $2,200.00 for a polish and application of Sharkhide. I never saw it when they delivered it back to him, but another friend who did said it was extremely well done. I saw him about two weeks later on the sandbar, and his toons looked like crap. They had already oxidized. The outfit that polished it said that they had applied Sharkhide, but it actually was never done. This was verified by the application of a small amount of Ducky to the aluminum. When the Ducky was applied, the aluminum turned further. Had the toons had Sharkhide, the Ducky would have no effect on the aluminum.
Long answer to a short question.
I would Google professional polishers located in your area, talk to them and get quotes, and get a few references. Also, your dealer may know of some good sources.
