Gloss showing through clear coat

I've had that happen to me, and I've never spot coated since. It is best to clear the entire model before decals. You may be able to go back with a gloss coat over the entire model, then go back with the satin after it dried. Someone may have a better idea, though.

After reading your response I see that my ideas wont really change anything. If I buffed over the gloss parts and then shot a satin clear it would still show the gloss. Enough coats of satin to hide it would be a lot of coats.

What if I sprayed flat on the gloss areas and then a final coat of satin?

 

Is the satin a semi-gloss, or eggshell?  If so, then a flat first followed by the satin may be the way to go.  Experiment- apply a scrap decal to a piece of plastic painted with the paint you used, then the two overcoats, and see how it comes out.  Testing yourself is better than relying on others results, your application style may vary things.

 

It's semi gloss. I've come to realize that it doesn't look that bad. No one will ever notice it, just me. I agree with Mississippi that the whole model must be gloss before decals.. Nothing I could do once I put the clear over the semi-gloss with gloss spots. So now my question is- Why paint military airplanes flat, then gloss clear for the decals instead of painting gloss colors first, decaling and then flat clear?

Because there are no gloss versions of many military colors. If the model is a pure black, or primary color, then I don't bother to use flats, merely, as you say, flatten it after decals.  But there are so many tans, greens, and blues for which there is no gloss available- you must mix it yourself, not easy to do.  Most military colors are very low saturation, almost tinted grays.  Paint manufacturers tend to provide only high saturation colors in gloss sheen.

 

One reason when Gloss shows through is that if you use rubber or cloth type gloves while handling the model it will cause a accidental rubbing and it actually polish the surface causing a gloss look.Also make sure you properly mix the overcoat amount .
