Hi there, you may be able to warm the area gently and try to push from behind and allow to cool down whilst keeping up the pressure. You will still have to carry out a certain amount of filling, shaping, primering, painting etc. Unfortunately a sucker wont do the job. the amount of time involved could take much longer than trying to find a s/hand bumper of the same colour and putting it on. I run my own small bodyshop so I see this kind of damage all the time..............hope this helps a little.
