Hi all,

I want to repair the hulls of a cat that have a series of large dent probably caused by contact with round rocks of about 6 to 10 inches diameter. They are not deep, most of them less than 3/32 of an inch. They are all located at the bottom. The hulls are foam cored.

I am wondering if I can repair those just by filling with gelcaot or I need to use a fairing filler then apply gelcoat? It is probably related to the depth of the dent so what is the maximum depth to use only gelcoat?

Thanks for your help,
