Before applying, take some sand paper or abrasive cloth and rub around where the holes are. Then cut appropriate size vinyl, apply adhesive on bunker then press on the vinyl. Id suggest holding it for a minute or 2 then let it sit out for the day and dry.
If you cant find any of that home depot usually has 3M Fc 5200 Marine Adhesive/Sealant. I had to use this and basically just cleaned up the spot and spread this around with a piece of like material over the top. Those things have lasted a few years now without coming off and are waterproof.
