If I leave mine on, and fix them, 'll need to do a bit of filling as well. I might do the same, fill them, wet and dry the filler and then the whole of the strip, prime it myself and then get the bodyshop to do spray and lacquer.
Getting them off sounds as if it could affect the door itself, which would be a disaster. I'll get the price for new ones anyway, but I reckon you are right, it might be best to 'make do and mend' as they said in WW2!
