First you need to clean the chip with something like Prepsol to remove any wax or sealant in the chip. Filling the chip with a toothpick is a good idea. You must go in thin coats, not one thick one. It may take several thin coats to fill the chip. I would allow 12-24 hours of dry time between each layer just to be safe. Fill the chip a little above the clear. Then you will need to level the chip, wet-sanding with a wet/dry sandpaper. I like 3M Imperial Wet/Dry 1500 grit. Wet-sand VERY SLOW. Don't go fast or you may go through the clear. Then once you are done wet sanding you need to compound to remove the sanding marks, some thing like 3M Perfect-It Fine Cut Rubbing Compound works well. Once you are done with that you need to remove the compounding marks with something like 3M SMR.
This can be a slow process, don't try to rush anything or you will not like the results you get.
