Wow, number 075! Ours are from the same litter (078 here)

Actually, since it's just the fenders that are chipped up, you could just take them off and feather edge the chipped areas and smooth with some good body filler, prime and then paint the whole fender black to match the gel coat. You can apply some of that clear stone chip guard like the roadster guys do. There are sheets and spray available.
