I used butyl tape to seal the holes when I drilled the roof of my Astro Van to add a rack to hold my solar panels.

I drilled the holes, cleaned the area with alcohol, put down the tape, and then bolted down the rack on top. It has been leak free for 6 years now. If you are leaving your factor rack off use a bolt and washer to fill the hole and provide for a solid cover over the tape.
