$50.00 Paint Job

[novanutcase]

I think I'm going to finally try the "$50.00 Paint Job" on my T-Bird and see how it comes out. One question, the car was painted with a basecoat/clearcoat and the clearcoat is flaking off. Someone told me that the paint has "oxidized" and I need to take it down to meatl before I paint it. Is this true or can I just sand off the clear and paint over the basecoat?
