Rear clam damage !

Hi, looking for some advice off you guys.
Did a very stuppid thing the other day, did some shopping, put this in the boot, went round corner too fast, tin comes out of bag and hits side of clam. This has now left me a web shape hair line mark on the outside . Any comments on best repair method for this i.e. will this just spray over ?
Cheers

no it wont just spray over. if it hasn’t damaged the fibreglass just grind the gel coat right back and either fill back with gel coat or if you dont have any filler will do.

I can,t see any damage to the fibre glass it looks perfect from the inside, its just the hair line marks on the outside, looks like taking it to bodyshop ! . That was a dear shopping trip.

depending where about on the clam the cracks are and how big they are it shouldn’t be a big job’ painting it is going to be more than repairing the crack.
