Have few 'oxidation spots' on the 92 SC400 I picked up a month ago. Are these really bad or the 'rubbing compound' suggestions on forums should resolve these? I mean does this condition needs new paint eventually? spoiler

That condition of top coat is very tricky to detail. A good detailer may still be able to save it. I'd use a Meguiar's M105 to start it off, and moving on to the M205 if you're successful. I won't use a wax to seal it though. I highly recommend a good paint sealant, specifically ceramic coating, I personally use opticoat on all my cars, and the finish is impeccable. It acts like a clear coating instead of just a wax, and is very effective for up to 3-5 years depending on vehicle use. Good luck!

IMAO that is too far gone...to make it look new, anyways. usually when the clear coat fails, its not rectifiable.

That looks like clear coat failure to me and the only real way to fix it is wet sanding, feathering the edges, and a respraying. I think if you try and polish it you'll most likely make it worse.

If it is a single stage paint and actual oxidation then you can probably polish it out. I wouldn't start out with something as aggressive as M105 though. I'd pick a mild cutting compound/pad combo and a low speed buffer to start as you can always get more aggressive if need be. There are plenty of youtube videos and detailing forum tutorials out there for you to reference.

+1 on Clearcoat failure. 100% this is what you're dealing with.

Oxidation does not occur on clearcoated paint, and that's what you have. You need a repaint. Cannot fix this with buffing or sanding.
