Hi Chuck, I have my boat in Mattapoisett at triad boatworks. The walnut was a lot less than $5000! They gave me a per ft number but I can't remember it right now. However, the complete bottom job start to finish with materials was about $5k to $6K If I pull my notes out later I'll give you better indications of cost. Danny

However, the walnut shell medium sounds like it may be the ticket if it is less invasive to the gel coat than soda blast and if I basically want to start with a blank canvas of a hull to prep and paint. ��Would love to hear from others that have used the walnut shell method and what they�ve done to prep afterwards.
