fixing a damaged 2013 soulcfaft fang tail

I have a 2013 soulcfaft fang tail that i that i purchased from the classifieds, and received it damaged from a member from this site. I will not go into details with the transaction. I have attempted to contact jeff at soulcraft and have not been successful, but this is not his problem since i did not purchase it from him. I just want some feedback on getting it fixed. I have had my stereo shop fix my 08 inland surfer board 2x times and you would never know it was damaged, but all the damage on the IS was on top not on the bottom. Are the materials the same? The local stereo shop said no worries to fix it. they said the only problem they see is you will be able to see the "fix:" since it is the traditional surf board look. My main concern is will it perform the same?
