Didn't like it for tough fishing conditions . I agree with Jaw . Using it as a sealer might be ok . Iwould finish coat with epoxy . I generally use Klass Kote . They will formulate it to the viscosity you need . Also on epoxy, If you mix more than you need put it in the freezer . This will buy you more time before it sets to the point you can't use it . Generally three days more or less .
