This is the method I use to make simple surround patches when one doesn't want to pay for a recone and just needs a "fix" to get up and running.
The other option is to sparingly use black silicone weather strip sealer like that by GE found in hardware stores. Apply it sparingly to the folds in the surround and next to the cone and spread it evenly around the perimeter with your finger, then let it cure for 24 hours.
