Ok i just finished repairing mine and it looks good ,like new ,ill say proudly.so here is a few tips for repairing those blades .first youll need some sand paper,stanley knife,masking tape.epoxy resign and hardner ,some carbon fiber matting,and a can of black paint. get your stanley knife and cut all the lose and cracked areas of the blade you wish to repair away,sand these areas with a course paper 80 grit.mix a relitave amount of epoxy resign to flill all those missing parts of the blade you just sanded.you should now have a nice mixed epoxy mixture ready to go. get a pair of scissors and finely cut peices of the carbon matting into the epoxy mixture until the resign becomes a paste all nice and black mix it well its now ready to be applied. take your SUP paddle and lie it on a work bench get your masking tape and place a peice of tape under each area you are repairing.get your carbon paste and place it in the areas you are repairing be liberal but not too much youll only heve a lot of sanding to do when it dries.now take your tape and fold it over making your edge if you dont have enough tape dont worry just add some more on to the existing tape i use the 3 " tape it covers larger areas.leave this stuff to dry about a day.you are now ready to sand using 80 to start then 100 then 120 followed by wet and dry 200 or 300 grit.your blade should now look like new . No .get that black paint out ,how about now? no luck bring it down to the repair shop at Amerilis and let me see what went wrong maybe i can help.Russell
