You can add fields from a manytomany relationship in a form using ModelMultipleChoiceField. This field is set by default as a multiple select box (i.e. hold ctrl and click multiple objects). You can change the field to a checkbox by defining a widget.

forms.py

class FinsForm(forms.ModelForm):
    fincompatability = forms.ModelMultipleChoiceField(
            # provide a label
            label = 'Fin compatability',
            queryset = FinSystem.objects.all(),
            widget = forms.CheckboxSelectMultiple)

    class Meta:
        model = Fin
        fields = ['name',
                    'fintemplate',
                    'finremovable',
                    'finbase',
                    'findepth',
                    'finarea',
                    'finsweep',
                    'finsfoil',
                    'finsize',
                    'fincompatability',
                    'finnotes',]
