Have you tried the BIG rubber sucker and pull technique?
When Junr dented the Punto I bought a couple of cheapo sucker things with a side lever that pulls back the rubber and forms the seal - they were c**p. I did a much better job with a LARGE sink plunger for about £2 from Howells in New Brighton. Worked fine. I used glycerine on the rubber to help it seal. KY Jelly would work fine PMSL
