Auto body repair & detailing: Fiberglass touch up, jeep wrangler unlimited, sharpie marker

Question
Just purchased a 2006 Jeep Wrangler Unlimited, and the hardtop (black) has a chip in the fiberglass that is showing white.  I have looked at Mopar, JCWhitney, 4WD Hardware, etc, but can't find any touch-up paint specifically for the jeep hard tops.  What do you think about a black Sharpie marker?

Answer
Mary Ann,The sharpie marker will work ,but it will take a few coats because it will look brown.A better solution is to buy an inexpensive aerosol can of flat black spray paint.Spray some paint into the cap and use a small paint brush to apply it to the chipped area.A small hobby brush for model kits etc.,should work well.Have fun in your Jeep and thank you for the question.
