Can my paint be saved?

[Stang_Crazy]

I have almost given up on my 89 GT. When I first got it about 2 months ago, it needed some paint work...BADLY. Nothing major, it just had ALOT of swirls and scratches.

After 13 coats of Zaino, a majority of the scratches are covered but there are some that look to be deep into the paint. Here's my problem:

My car doesn't have a clearcoat. Since it doesn't have any clear, I was scared away from wet sanding...afraid of sanding down the paint and dulling the color. So should I try wet sanding even though I don't have a clearcoat?? If I can't find a solution, I'm going to have the car repainted next spring with some nice ghost flames and LOTS OF CLEAR!!
