i have been using a new product of my own,,,it's called,,,"Pumpkin Patch",,,it's just what the name means,,,some of the members of PGPGA have been using it and have recored good results,,,it heals the crack,,,but one draw back,,,your pumpkin has to be still growing,,,i used it last year on acouple of mine,,,did the job,,,if any one needs some i still have a few free packs left,,,
