Before you apply any more paint clean the body with rubbing alchohol. This will remove any oil fron your fingers and/or mold release. Fisheyes are generally caused by some sort of oil that the paint will not adhere to, including finger prints. The paint draws away from that spot.
When the body is clean sand it smooth, that is the paint you already have on the body. Clean it again and do not touch the surface you are going to paint. Apply additional coats as necessary to finish the model. If it is a solid color, that is non metalic, you may be able to touch up the spots as necessary.
If you are using an enamel let it dry for a few weeks before you use the finishing kit. Enamel stays soft for a long time.
