Marine Tex is good stuff, I have used it before, however, I just went through the decision process of what to get for a "large" repair. The only difference between what you described for damage, and mine is that my boat was taking on water...fast!! I had a good 6" long gash in the hull right in the middle of the boat. It is an older boat, but has high sentimental value, and I was really bummed out that the boat was junk because it just wasn't worth putting the money into with a professional repair. I went on line to look at different options for fiberglass repairs, and my research narrowed it down to Marine Tex, or 3m Marine high strength repair filler. The only reason I went with the 3m filler is because it has fiberglass in it as well, and I just thought it would "bond" better, fiberglass to fiberglass. It has been about a month now, and I have been out on the boat 3 or 4 times, and I can't speak highly enough about this stuff!! It's hard as steel, I mean rock solid, and haven't had a drop of water come in, and seems to be good as new!! The patch is right on a chime that goes over one of the roller's of the trailer when the boat is launched, and retrieved, and it is holding up just fine. It dries a greenish color and really stuck out on a white hull, so I got a can of white flex seal and sprayed about 5 coats of it on the patch and it matched great!! I feel very good about it being a permanent repair, but will be keeping a close eye on it... I would definitely recommend for a temporary fix for a 3 year old boat, but I would consider getting your's fixed professionally for a boat only 3yrs old, that's up to you... BTW, this 3m stuff cures in about an hour!!
