<p>Thanks for your review. The undercut edges are designed to be trimmed away to fit the over fender to the body. The fenders themselves are designed to be blended into the body.</p>
<p>For example, the front fenders are meant to sit flush with the body. The decision to leave it looks fine, but may affect fitment.</p>
<p>Perhaps we can provide a diagram or trim for future reference.</p>
<p>Traditionally, fiberglass is not shipped primed, since most painters will still perform their own prep work and apply their own primer as a rule of thumb.</p>
<p>Thanks again for your feedback!</p>
