    Default Re-Gelcoating a Boat

    Got a quick question found a ton of information on Gelcoating a boat but wanted to get some opinions though.

    I want to re-gelcoat a 17ft from top to bottom. I was thinking of going about this way.....

    Mix the gelcoat then use a larger painter roller to roll the gelcoat on, let it dry then do a finish sanding on it. Any spots that I missed roll back over and repeat. then buff and wax it.

    Would that work?

    Will it work....yes...sort of...but not really.

    Gel coat does not level or flow very well, especially when applied with a roller, so you will need to sand off more than 50% of what you put down to try and get it level, and even that may not be enough to make it look right.

    Re-gel coating an entire boat is a huge job, so you need a good reason to do it.

    The boat is the 2 tone brown and tan and do not like it at all. I was going to cover it in aqua white with a blue stripe. Then what is the best way to do this?

    Rollers and Gel do not work .. spray the gel or paint it ..

    17' of a gel job is not that hard.. if you know what to do and have the proper materials and tools/guns. ..

    Mask off the small tone .. spray your big coloir .. unmask the stripes and blow the gel ( yes with overspray and all ) over your stripes .. then sand down your stripe color line until its "there" ..

    Painting is actually another Iboats debate on difficulty level .. little harder in the long run of the finish coat for this size of a boat .. ( Pics again please ).

    Gel Is gel .. Paint is Paint ..

    Know your pros and cons of each before you decide .. its apples and oranges m8 .... .. ..

    even tho i do full gells.....

    EDIT>>>>> i think for a first timer....a paint would be the way to go here.<<<<<<< edit

    .the auto guys laff at me....>>>>EDIT....over the amount of work that a full gell is....<<<<<<edit



    the prep is prep.....no way around it.......then the shoot......but after the shoot...they clean thier guns and go drink beer.

    that is when i am suiting up with the respirator for a few dozen hours of sanding..... !!!!!....

    but i must say.......i believe gellcoat is a far superior product for a boat...

    put your chevy in the middle of a bumper car ring filled with solid wood posts and then make the whole thing move to emulate a boat tied up at the dock and see what happens !........your chevy will be total junk......and a boat lives thru that every day,,,,

    oh, geez....now im getting started on an auto materials being used on boats rant....dont get me on that track....lol..

    It is rarely worth the time, effort and money to re-gel coat an old boat, some old classics that are being actually restored to original condition may be worth it, or if the boat is of enough value to justify the cost it could be a good option. But for the most part the boats being discussed here were purchased for a few hundred bucks and the budget to get it back on the water may not even be that high, so investing that kind of cash and time on gel coat would be a poor use of available funds.

    That's why this statement was used in my first reply

    "Re-gel coating an entire boat is a huge job, so you need a good reason to do it."

    If this person is going use a roller to apply it, I think I can safely presume there aren't sufficient funds to buy the correct tools. Thereís nothing wrong with that, but you need to pick the correct places to put the cash, and typically the motor is a much better place to put it.

    I have re gel coated plenty of houseboat decks with a roller. Its fine for that, but I wouldn't want to roll a run about.
