Snowmobile tunnel cleaning

Someone mentioned 'wet sanding' the snowmobile tunnel first, then Busch.

What grit sandpaper?

Any other tips?

the sandpaper grit used depends on the shape the aluminum is in. if you have some pitting from excessive oxidation or scratches, you can start with 240 grit and work your way up to 320, 400, and then 600. If the aluminum is not bad, try 400 first, and see what you get. it needs to be basically perfect so when you start buffing so it will come off clean.

after sanding, go with Tripoli compound and something like our yellow 6" airway pad on a drill. Finish up with Busch Super Shine and a 6" white airway pad.
