I got a new tailgate, windshield frame and necessary gaskets/moldings for my gals 93 yj. She would like to have the new parts installed asap but we are not planning on painting the jeep until this spring or summer. Will the protective coating/paint hold up or should we get these two pieces painted prior to install and repaint the entire jeep later as planned? How much prep work is involved and can a decent job be done by a novice? Thanks, Frank
