After another weekend of getting the project boat (Catalina 22) in shipshape I came across another problem. Where the silver support arm attaches to the pop top it came loose. There are only two small screws that went into fiberglass. So now i need an option for what to do with holes so they will hold screws again. Which product would you suggest? Epoxy? if so which type, fiberglass repair? if so which type? Also these are not through holes.
