    Default Painting the bottom of a speed boat

    I am fixing up speed boat (Fibre glass) and want to paint the whole hull/boat. How do I treat the bottom before I paint it? What paint do I use? should I use a resin or resin based paint or epoxy paint? advise and tips needed. Regards

    The boat is white at the moment and I want it black. It's a long project / hobby. It will take a long time. I don't want to rush anything , it must be perfect.

    I don't know if paint will last ??

    The best would be to apply a layer of black gel-coat... (Black fiberglass resin)... It will bond perfectly and should last !

    I've been told to keep hull colors white or light colors , the reasons im not exactly sure but has to do with heat softening (fiberglass resin ) , hull tempreture ,u.v. degradation & oxidation . Docking and beaching ur boat might leave some very visible marks on black .

    Might be a good idea to get professional advice.

    I think the "reason" for keeping it white... Is more with deep sea fishing boats, where you have a chance of flipping the boat...

    A white hull will be more vissible by rescue boats

    This is a great subject.

    Lets see now.

    A boat is most likely to flip or get into trouble when the water is rough, ne.

    And when the water is rough it is full of WHITE horses, ne.

    And when the helicopter is search for you your WHITE hull is going to very visible amoungst all the WHITE horses - NOT.

    Thats why rescue craft are ORANGE - visilibilty at sea.

    EDIT - that is why a large ORANGE plastic sheet is part of the safety equipment.

    agreed , reading some of the other forums - coastguards moan about this often as they would prefer brighter colors for all boats

    No it's much simpler than that - have you any idea how hot a black boat can become? And then you have to sit/stand on that (normally with little clothing for protection)

    Here's a snipbit from some googling ,

    another side effect from a professional boat painter

    There is one important factor not yet mentioned on this thread. On a fiberglass hull the extreme heat caused by dark colors causes the glass to shrink over time. This causes what we call "print-through". If you walk down the dock in your marina and look carefully at any dark glass hulls you see, you will notice that you can see the weave of the fiberglass through the paint. If a boat has been faired at any point in her life this problem is exacerbated by the different shrinkage rate of the fairing compound and the glass. If you look at Interlux' painting manuals there are temperature ratings for different colors in exposure to bright sunlight for long periods. Flag blue is rated at 280 degrees fahrenheit! Thats like putting your boat in an oven for months at a time. While it wont "soften" or structurally damage your boat in any way, it will make it impossible to keep a fair hull.

    Use a polyacrethane twin pack paint (we use Plascon)with a sigma cover primer which is epoxy based, the colour is up to you allthough all of the arguments above are valid. Should you need any specific advice give me a shout on [email protected] and Ill send you my number, I am a boatbuilder by trade and can give you unbiased advice based on many years experience.
