depending on the level of oxidation:
step 1: Using a good rotary and oscillating wheel apply rubbing compound (medium or heavy - I would try medium first).
step 2: After removing the rubbing compound, wash the entire hull with Dawn dishwashing detergent.
step 3: Apply Collinites 920 cleaner. apply with the buffer, remove by hand and then polish with with the buffer using a microfiber pad.
STep 4: Apply Collinites 885 paste wax. apply by hand, heat up with the buffer, remove by hand and do a final polish with the buffer using a microfiber pad. if you really want a long lasting application perform this step twice - allow 12 hours between applications.
My 360 is 11 years old. It looks like brand new. People at the marina cannot believe the shine - even compared to new boats. I have used this process forever and it works. if you don't have a buffer - you need one. I suggest the Porter Cable. good luck.
