you need to flat the edges back , this involves getting some 600 grade wetting sand paper . Flat back all the loose edges of the laquer until you cant peel it any more , the edges need to be feahered in to the underlying base colour coat , filler primer the damaged area , flat with the 600 paper the whole panel then will need to be re base coated and re laquered , this is if you want a mark free finish to the panel .
