Severe Oxidation

I'm trying to remove the oxidation from this 85 RX-7 and it's going ok, taking quite a while. Here are the pics below.

So far I've used megs CPC to remove the oxidation and then #26 wax just for the picture.



My problem is that after i'm done with the CPC the paint still isn't very shiny, and i don't think the problem is that it is too course. As in I don't think a milder polish would help. When I wax it, it still seems to soak up a lot of wax. It seems like it's a matte finish and i'm trying to get it to look glossy.



Has anyone been able to get a good shine out of paint like this? I may try and polish it but it's taking so long to remove the oxidation I just don't think I want to put that kind of time into it. I'm selling the car on ebay and probably won't get more then $1000 for it.



Any suggestions would be helpful, thanks.
 
From the looks of the pad that's laying on the hood, you aren't getting all the oxidation off and it's transferring when you apply the wax. That's also more than likely the reason that it's soaking up the wax that you are applying. You may need to do a little more with the CPC or you may just need to work it with DACP to clean up more. Could also be that this is two stage paint and the clear coat has failed. It's really difficult to tell from the pictures that you included but those are my guesses from what I see.

It's old paint and definatly not two stage. I'll try working it a little more with the CPC and maybe some DACP and see what I get.



From my past expirence single stage paint in bad condition tends to rub off very easily so I'm not convinced that there is more oxidation there but I may be completely wrong.
 
True that it would rub off easy but if I remember correctly that that is rubbing off is dead/oxidized. Give it a little more work and see what happens. I think you're on the right course.



On another note. How is the buffer acting with CPC and a foam pad? From what I was told, it would jump around a bit as the CPC was meant to be used with a wool bonnet.
 
That's one of those tough colors to bring back. I also don't think you're as done polishing as you think you are. Anything showing up on the wax pad is proof of that.
 
I actually read that CPC was supposed to be used with a foam pad while the Diamond cut was supposed to be used with a wool bonnet. It definatly jumps around a bit, but generally just the first time I go over the dead paint. After I've got most of the dead stuff off then it's fine.
 
Also, this paint isn't exactly in good condition so what are the chances that I'm going to end up hurting it permanently if I polish it too much? What I'm thinking is that there may be no good paint left.
 
Right off the bottle under tips:

For best results with a high speed rotary buffer, apply with a Cut 'N Shine Wool Pad (W4000)
 
There is a chance that you will do permanent damage and there's only one way you're going to find out without a paint gauge. Other side if the coin is that it will still look better than it does and allow you time to sell it.
