Not sure if this is good idea against someone strong, iron shirt or great internal strength.
Wingchun is probably more direct on this.
Punch people with internal power b4. Believe me, dont think this gonna work.

For shape of Bagua palm, try Mr Xu ShiXi, he is an GREAT expert! He s got it.
Everyone should go visit him and ask him questions as much as possible.
Even if you cant afford it, just visit him and ask any question.
He is nice guy, and ask questions humbly.
