Preciselely. A bodge that isn't good enough always costs more.
I would peronallly for gas be more inclined to get a bit of car body filler and some bandage and wrap the gas pipe with that.
I have never found droppong a blob of solder over a pipe hole seals worth a damn. If the flux works and the solder flows, it doesn't cover the hole. If it is blobbed on, it is not secure or gastight.
