I have a 97 Mustang GT red in color which had clear protective film on the front most edge of the hood which over time cracked. I carefully removed it with a heat gun. Now there is a glaring color shade difference. I have been told the only way to equalize this was to wet sand and rub out the hood. Would using the medium Nanaoskin mitt and clay liquid spray correct this or do I have to wet sand and rub it out?
