I have a 23 foot Sunrunner. Today I noticed numerous cracks in the gelcoat on the bottom of the boat. It doesn't look like blisters(bubles).I took a knife and was able to peel the gelcoat off. What is the best way for me to repair something like this? gelcoat patch or marine tex? I am trying to lean away from bottom paint due to I trailer my boat at least 6 times a season(six months).Is this something I should be worried about? The hull is white so a perfect match in color is not a priority.
