Doing a 1/8 E-Type Jaguar kids got me for father's day. Great car, love the build but I'm new to getting the paint right. Using Tamiya primer, fully sanded car before priming, new expensive airbrush, SMS paint and clear gloss. After clear coat and polish I'm still left with this "orange peel right in the middle of this part. This part goes under the car so it was a test run for my skills but want to get it right before I start on the body. Is this dust on the part after priming before paint or just my lack of skills. All help appreciated. Extra photos to show off.
