well i have the hull of my first airboat built,,,motor mount installed,,,ill have pics soon,,im ready for some sealer?? epoxy?? primer???and paint,,,,any suggestions...dont really know what the best things to use to preserve hull from water and gas,,,looking for a july 4th launching,,,so far so good,,any help would be greatly appreciated from you master builders,,

is it made out of wood? if so, some polyester resin will be a good coating...if its foam, epoxy resin then...

epoxy resin is best you can use it on anything and its more durable!!.
