Ben Wenberg first put tape on the backside of the trunk floor board over the holes. Then applied a coat of POR-15 to the floor board. Then immediately laid 6 oz. fiberglass matting on the wet paint. Then immediately applied another coat of POR-15. A really strong repair when finished. Yes, you can try this at home!
