A suction pad tool will not pull a dent that small.Leave it alone and wait until someone makes a bigger dent.

Our local dent man charges £50+/- for ironing out parking dings - he even did one for free as it was not as good as he usually manages - nobody would see it unless you pointed it out.

A few bent wires and a good eye keeps the ££s rolling in for him - he spends 90% of his time in the local garages sorting out "new cars" and trade-ins before they hit the fore court,
