mottyman Posted July 19, 2006 Share Posted July 19, 2006 Hi Netic, You need to use a Silicone that won't hurt the alloy and this one wont. Selleys Roof & Gutter Silicone Sealant - Translucent It comes in a 310gm cartridge , one of those that fits into a dispenser gun with the trigger, the cartridge is blue on the front with green writing , green on the back. I use this on my boat and have it around the screw holes on my transducer bracket. It's been there for 10 months - no leaks or problems at all. Cheers David.

Guest rzep Posted July 19, 2006 Share Posted July 19, 2006 If it is a glass boat then any marine silicone will do the job. Regards Paul Link to comment Share on other sites More sharing options...
Lightweight Posted July 19, 2006 Share Posted July 19, 2006 Hi Netic, Try Duralac Jointing Compound, you can get it from most chandlery outlets. It is the best stuff in that type of situation. LW Link to comment Share on other sites More sharing options...
netic Posted July 19, 2006 Author Share Posted July 19, 2006 Thanks all, i was hoping i can get the sealant from bunnings, save me a big trip And its an Alum boat Link to comment Share on other sites More sharing options...
Guest Jewel Posted July 19, 2006 Share Posted July 19, 2006 Any sealant that you use on a tin boat needs to be non acidic/corrosive, most household ones are not. Sikaflex has a huge range of HIGH quality sealants, Sikaflex 291 would probably do the job for you quite nicely. http://www.sika.com.au/home/cmi/sikainside...ducts/index.htm Link to comment Share on other sites More sharing options...

LW Duralac is designed for use in situations where you have stainless steel in contact with aluminium and it reduces any chance of corrosion between the dissimilar metals. At least that's what I always thought?? Link to comment Share on other sites More sharing options...

At least that's what I always thought?? Yep, that is correct you should always use Duralec when putting dissimilar metals in contact with each other. I am not sure what sort of boat Netic has, i may have made a false assumption that he has an alloy boat of sorts. Just to be sure, it certainly doesn't hurt to coat ALL bolts that are going through metal or a metal fastening plate with a little bit of Duralac. If you have a glass boat then the silicone product of your choice will be fine. LW Link to comment Share on other sites More sharing options...
Guest Big-Banana Posted July 19, 2006 Share Posted July 19, 2006 We had some electrolysis on our boat, where the screws meet the aluminium. So now we have used the Duralac and are in the process of touching up all the affected areas. It seems to be ok for now. When my old man was up in Nth Queensland, he went into a boating shop and explained the problem we were having. He recommended installed Anodes on the actuall hull, which we have done. Iam a bit dubious but do you fellas think it will work? Link to comment Share on other sites More sharing options...
