Over the last several weeks I have purchased some 3M compaund and with the use of a power buffer have been able to remove most of the oxidation on the graphics on both side hulls. When I first did it everything really shined but over time I have been noticing the oxidation is starting to come back with that chalky look. What would be the next step to prevent this from occurring? My graphics are built into the gelcoat and are not plastic taped on and the colors are dark such as purple, black and yellow.
