I'm detailing a 35' donzi with some pretty bad oxidation, on the starboard side there are a couple patches of damage that are worse then the rest of the boat. Any ideas what causes this or how to repair?
Could you get some pictures that are farther away? how large are those spots. Could the whole starboard side be buffed with polishing compound? Try some McQuires Ultimate to cut some of the oxidation away and bring back some color.
