    08 RXTX Pump Tunnel DIY'ers

    This weekend I am going to tackle the pump tunnel in my 08 RXTX. There are no cracks and I want to keep it that way. I have gone through the thread on this site and have watched the videos on YouTube. I basically have 2 questions:
    For a basically Stage 1 ski is fiberglass OK or should I use carbon fiber?

    What did you pour in the void after you removed the crappy foam stuff between the inner and outer hull?

    West System resin and hardener between the hulls?

    The rest looks pretty straight forward. I went to West Marine today and bought West System Resin and Hardener, fiberglass sheets, brushes and squeeges. I also bought a bilge pump and switch. Thanks TJCIN

    I filled the void about half way with resin/hardner, dropped in some patches of carbon fiber, added more resin/hardner until the void was completely filled. The next day I added 3 layers of carbon fiber over the pump tunnel. The carbon fiber is overkill......fiberglass will work well and its a whole lot cheaper.
