I have an inflatable C-C 3 Polyform (red) mooring buoy

US made. I do not know what is the material it could be vinyl, poly or
others.
I accidentally made a nail hole in it. I wonder if it could be repaired.
TIA

I *once* found a fender repair patch kit and used it
successfully but never saw one again.

Found this on Polyform's web site!!!

Polyform patch kit#20 PATCH KIT

Polyform supplies a patching kit for repairing small
punctures in buoys and fenders. This patching kit is very
successful when used for these types of repairs. Large cuts,
or repairs to buoys and fenders used in extremely severe
applications may not patch successfully. If there is a
question or concern regarding repairs, contact your local
Polyform representative or call the factory directly.
