Replying to General epoxy questions

hi, i have 2 main epoxy questions, what epoxy would be good for protecting topsheets from chipping / filling in old chips. I know that i need something flexible and long cure, but my marine epoxy i found lying around is white and i want to buy some new stuff.

Also, how do you epoxy edge cracks? Like how do you physically transfer the epoxy from stirring to inside the ski? Pouring it sounds like a bad idea. Use like an old playing card or something? Thanks for the tips
