I can not afford a new paint job at the moment and the current one on my Z has seen better days.

I've got scratches here and there, swirls in the paint and the clear is fading on the hood and such.
While this doesnt bother me as a whole, is there anything on the market that can help?

I just washed and waxed the car and barely saw any difference other than it's clean.
I literally put three coats of NuFinish on the hood and just see no difference.
