I ran across this video on how to fix gel coat. Looks like wouldn't be very hard, (a lot of things aren't hard if you know what you are doing.)
Fortunately I don't have any need for it right now
but after the season is over who knows, s--t happens!
I have never tried to fix the gel coat, but I know several people out their with issues so this might be worthwhile.
If you have done this yourself then please let the rest of us know if the process is as easy as the video shows.
