Boat question (Page 1/1) Csjag AUG 20, 09:30 AM The Bonito boat I just purchased had a lot of small screw holes in the fiberglass interior where things used to be mounted. Does any one know of a good patch in a tube that I could use to patch these small holes? Preferably white because the fiberglass is white. Thanks jaskispyder AUG 21, 12:24 PM Silicone? Otherwise, something like JB weld, and paint it to match. CoolBlue87GT NOV 22, 10:22 PM Check with a local marine store, there are some epoxy's that are white that will work for your need. PaulJK NOV 23, 08:07 PM BrittB DEC 09, 05:05 PM JB Weld is epoxy based, I would consider that as long as it's not in the hull itself. weaselbeak DEC 11, 11:21 AM quote Originally posted by PaulJK: I used an entire can of flex seal on a small water tank that leaked a little on a seam, with a couple of microscopic pinholes around the edges. I am not impressed, I could have done as well with paint. rogergarrison DEC 20, 04:53 PM Check with any local boat shops. They have a catalyzed gel coat for fiberglass boats. You mix it up like body filler and its precolored. I have a buddy in the hull repair business and watched him do lots of it. Uses same thing (to teach me) for fiberglass RV skins. I used it for RV repairs for a dealer here, and also repaired their Wellcraft boats they sold. If you have any trouble finding it, call Spooner Marine Service, Gahanna, Ohio and ask for Dave.
