If the aluminum is really dull you may want to start with an acid solution to get it clean prior to polishing. You can purchase acid for aluminum at most tractor-trailer vendors. I used to use it on my Bass Tracker and it really cleaned the black off. You mix with water in a bucket and use a car wash brush.
take it to a semi truck wash,have the use the acid wash they use on semi fuel tanks and wheels.
then get blue magic aluminum polish (at the truck stop) or mother's
and a power buffer.
thats how the tanks and wheels look so good on semi trucks
yes ,you have to break the oxidation off of it, then polish it. thats how those wheels and fuel tanks on semis look like chrome.
use a buffer you will get a deeper shine then put a coat of good wax on it to seal it.
so i will need to give it a acid bath then polish and buff? i work for a company that builds aluinum trailers sometimes we have to acidized the ones that come in for repair. maybe this is the same acid? i'll ask my boss for some and try it.
Now Thats A Shine!! That Is A Little Shiner Than I'd Like, But It Does Look Good. I Dont Think My Bass Tracker Would Ever Shine Like That! I Used Some Acid Today. I Sprayed It On And Let It Set For A Few Minutes And Sprayed It Off With A Garden Hose. It Cleaned A Lot Of The Black Off But Now It Is Streaked! I Am Going To Try Some More Acid And Use A Brush And A Power Washer Then I Will Get Around To Polishing And Buffing. Wish Me Luck!
When using the acid solution, you do not want to let it stand. If you mix according to the directions, use a car wash brush and elbow grease. If you wash an area top to bottom and spray it off with water it should not streak.
