This is now your patch. Next you need to put larger pieces of fiberglass to cover the patch and an extra 2-3 inches to reinforce the patch. Sand to remove and rough areas and to look clean. Then a final sanding and a last coat of gel to cover everything and seal the repair area. Between each step the masking tape is being replaced. More then half a role of 1" and 1.5" tape was used. Don't use cheap tape. Use 2" pieces starting from the outside and then use 1" pieces to finish off the inside. This way you just need to remove the 1" pieces each coat and keep the 2" pieces saving both time and money.
