Great advice Picus! Before I leave for the week, the only other things I can think of is to make multiple fills while waiting a few hours between each fill. Also, buy / use the
Meguiar's Unigrit sand paper as opposed to other brands you may find. Make sure the sanding area is properly lubricated and sand in one direction. There's many good tutorials on this if you search for them under terms like "scratch repair" or "chip repair", etc. Havea good week and I hope your repair turns out perfect.
