We have the same color MC but ours is a '94 190.
When I buffed the boat this summer, I was able to get all the oxidation off and buff to a nice shine with glaze and then wax.
I think the part I missed was the sealer...what did you guys use? I watched the video but was not sure exactly what is was...i was not able to keep the deep luster that's why I am think the sealer or protectant was the key I missed. I will try it again once the weather gets warmer.
