Bow and Keel Gelcoat Repair
3430 has all the gelcoat worn off the lower bow where it turns down under the boat. The section is about 2" wide and 16" long. The fiberglass is glossy and shows no fiber. I have sanded it all down with 600 wetsand emory paper, so it is smooth. I think this is bad to have in the water. (my boat sits in a wet slip), and should have Gelcoat added. What do you think is the correct step?
