    FINALLY got around to doing this.. not the prettiest but now I’ll let it dry, then sand down. I added some 410 which is why it looks goopy.
    Then apply some Bottom Paint I guess. Either that or some gel coat touch up if I can find something similar in color.

    And sanded.. looks pretty sweet. Not a pro but.. It’ll kill ducks!
    I just can’t find any paint to match up. Most bottom paints are blue, white, grey. No marsh colors for us duck boats?

    Can I go ahead and put it in the water now, or do I have to paint over? I used West 105 resin and hardener.

    I wouldn't put it in water yet. It will soak up moisture and take a while to completely dry out.

    I'd skim coat it one more time a little wider out and get those dimple spots missed around the edges of your patch and then sand her smooth.
    Told ya, there isn't anything to it

    I just used the bondo fiberglass gel for a repair on my boat a few weeks ago. I'd say the gel would work better on a vertical surface than the resin. The texture is kinda like mayonnaise or a very thin peanut butter. It's easy to work in the cracks before it sets up. They sell it at Walmart.

    Seriously! And to believe that I was getting quotes from $300-$400 ! It cost my $40 and 1/2hour time.
    Now that I’ve done that, I’m gonna fill in the rest of the dings and then repaint the entire outside.

    I’ll get to that one day.. haha

    I’m about to get started on sanding down the outside but I need to know, what do I need to do after I peal off the registration lettering? If I sand over it will it be fine? I’m worried about and glue residue that I may need to clean up. Acetone? Paint thinner.. ? What’s best here

    Just wet sand it to get the residue and trash built up off.

    I do believe you would overthink tying a shoe.

    cleaned with acetone, sanded with 150paper and first coat rolled with foam roller. I’ll let it sit overnight and get second coat on after. It came out lighter than the original color, I’m contemplating on taking it to Home Depot and having them try to add a drop of brown to it.

    Finally got all the crazy led lights off the front of the boat. Now I am stuck with holes everywhere!! I have attached a picture below but wanted to know how to go about patching this type hole.
    The last areas that I did were only scuffs and not through holes. I saw some videos online and one guy used cardboard piece inside the hole and one guy just made a circle of fiberglass, put it over the hole and covered it in epoxy.

    Any better way that anyone has found to create a good backing and fill these holes ? I wasnt too sure if the guy who used the carboard was just using it as a backing and then took it away, or just left it. Its not a very wide hole but I feel like I need somethin sturdy in the hole, or will a few layers of fiberglass hold ?

    Should I use straight epoxy/hardener or would I be better off adding in any filler compound? YouTube you see a lot of crazies out there, I don’t want to half ass it, I’d prefer good recommendations.

    If you already have the stuff use epoxy, hardener and 406 or something around there. Taper the hole edge to increase bonding surface area and put a piece of masking tape or something on the other side. Fill it up, let it dry, prep, paint. Or you could use marinetex if you don’t already have all the stuff.

    The easiest way is to soak a dowel rod in epoxy then jam it in there, once it dries fill whats left with epoxy.

    The other way is take a grinder and dish it out, begin laying layers of mat overlapping until it is built up. Sand then use an epoxy fairing compound to finish it, then paint.

    Does the epoxy not stick to the tape? For the hole on the right I can do that, just wasn’t sure about the tape actually sticking.

    The hole on the left has foam all in it so I’ll definitely try the dowel out on that.

    Thanks guys

    Exactly this or if you can get your hand underneath and inside thru an access, wet a piece of cloth in resin and stick it across the holes from the underneath inside. Once it dries, your holes have a floor and mix some resin and chopped up cloth and fill it, sand it and gel coat it if you want it done right and a perfect match

    I’ve been kinda busy lately but I just got around to sanding down the second coat on a few spots. i would say I got this thing down alright. No pro, but it all came out smooth and looking good. The pictures may not look as smooth but they are clean.
    Now I will wait a few days and paint the entire top rail. I was able to patch the large holes that were for LED lights. Smoothed our the side rail where someone must have stepped and cracked it, then filled some cleat holes and other misc holes.
    Thanks for all the help here

    Good stuff!
    Get some fairing compound and clean it up a little more before paint. Especially the second picture.
