I work at a body shop and have easy access to it, but wetsanding and buffing is the best way to go about it....A friend of mine bought a boat that was heavily and I mean heavily oxidized and I made it shine like a new penny....It took some time and a lot of elbow grease but it looked great....He sold the boat almost 2 years ago and it has been stored outside since and still looks nearly as good as it did when i got done...Taking the top layer off and then getting it sealed down is the only real way to restore the shine...Waxes may shine it up but it will quickly fade because you haven't removed the source of the problem
