  • As long as the boat is not going to be left in the water for a long time you should be ok, preparation is everything so give it a sanding with 80 grit paper using an orbital sander making sure you keep it flat so the edges don't dig in then wash it down and let it dry. You will need to primer the boat first I like INTERNATIONAL PRE-KOTE primer and TOPLAC for the finish but there are other makers out there, it might take 2-3 coats of primer to build up a smooth finish then use 240 grit to flatten it out before the top coat, applying the top coat I use a fine roller followed a dry brush or foam brush to flatten out any lines " its called Roll & tipping" and will give you a good finish you can get a perfect mirror finish if you want but it's a lot of work going through different grades of paper going from 500 grit 800,1000,2000,3000 and then rubbing compound and waxing.

    Best of luck with it.

  • Great advice from Fergal. In addition I’d recommend putting half the total effort into the cleaning and preparation before using a single brand for primer and topcoat and above all else, make sure you take your time and don’t try to rush any steps.




  • Also, if there's a Vinny Byrnes Autobody Repair Supplies shop nearby, get a box of tack cloths. They are only around €7 and you use them to wipe down the hull to remove dust. Or a clean lint-free cloth wetted with some thinners is also an option.




  • as Donie75 said get some tack rags. gently rub them over the undercoat just before you apply the topcoat. if the boat is outside try not painting on a windy day. in summertime dont paint in the evenings as the midgets are attracted to the smell of paint and the will ruin your work

    Yep best to remove all the old paint and start with a clean canvas.

    As long as it not going to be left in the water too long it will be fine to paint top and bottom.

    I like to sand between coats with wet 240 paper to give the next coat a key to hold on to, this is one of my builds with toplac on the bottom.

  • Remember to protect yourself some of the paints and fiberglass dust can be very harmful to your lungs and very irritating on the skin.
