Answers.Body: <p>I would tend to suggest another non-waterproofing solution - build something to hold your ship from underneath, that will safely rest on the bottom of your pool.</p>

  <p>I owe that idea to a Stargate SG-1 episode I rewatched recently, actually.

Answers.Body: <p>I suspect that water leaking through the hull will not be the real problem you need to solve. Granted, I haven't seen a photo of what you have built, so I might be wrong.

  <p>If you go look up some of the old sectional boats that they made in the mid 1970s, they all came with lead filled keel piece to keep the otherwise light and rather top heavy Lego boats from capsizing.

  (Asked by: username_0 on 2012-10-16)
  
  I have a LEGO ship that I want to photograph as it's sailing along in a pool. Of course the LEGO bricks have cracks in between them so water will leak through.
  
  Does anyone have any ideas as to how to waterproof the hull? Something that won't harm the bricks that can be easily removed. Also I don't want whatever the material is to be visible in a photo.
