could just wetsand the edges of the laquer where its lifting, to remove any loose bits. Mask around it and spray with a can of laquer, then wetsand/polish the area till its flat (after its dried for 24 hours or so)
then get polishing the rest of it to try and stop it standing out too much.
not going to look great, well it might if you're any good at painting with a rattlecan.
