Bob,
FWIW, I paid $1500 to have my 35-3 soda blasted. Worth every penny!!! Jake Jake Brodersen C&C 35 Mk-III "Midnight Mistress Hampton VA From: cnc-list-boun...@cnc-list.com [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Bob Hickson Sent: Thursday, September 06, 2012 12:59 PM To: cnc-list@cnc-list.com Subject: Stus-List Antifouling removal - chemical strippers Thanks to everyone for your feedback / suggestions. I do not think that a pressure wash (high pressure) will work well on antifouling without damage to the gel coat. My boats have always been pressure washed in the fall by the yard after haul out and this certainly does not remove the bottom paint. Higher pressure might work but at the expense of the gel coat. I power sanded the bottom of my previous boat (Viking 28) and I am not anxious to repeat this experience on the 29. I had to sand the previous boat in mid winter because it had VC Tar under the paint and this cannot be sanded unless it is cold (it smears and blinds the sandpaper in warmer weather). I have a quote of $1,800 to soda blast the 29-2 .... seems pretty high. Have a second quote for $600 from a contactor that is going to use a wet sand blasting approach with very fine sand. I am a bit leary of this approach since I hear that you can do extensive damage to the gel coat / fiberglass by using sand. The sand is reportedly too aggressive. I am waiting for a quote from a contractor that can do dry ice blasting ... this sounds like a great approach since there is no blasting media to clean up. Will let you know what his price is. So far nobody has said very much about chemical strippers. I would like to know a bit more before I make a decision. The Franmar website has an interesting video (second link) about using their product "Soy Strip" http://www.franmar.com/industries/marine-boating.html http://www.franmar.com/videos/43-product-videos-bottom-boat-antifouling-pain t-removal-soy-gel.html Was hoping for some firsthand feedback on this product or other chemical strippers. Looks like a choice between dry ice blasting or Soy Strip at this point Best regards, Bob Hickson, P.
