raz88 96 Posted May 13, 2017 Share Posted May 13, 2017 Is there any special prep coating or similar required to make sure it sticks? Or just make sure the surface is flat and clean and go for it? Quote Link to post Share on other sites

idlerboat 116 Posted May 18, 2017 Share Posted May 18, 2017 .....The thickness of the tape is important. If you have long windows the expansion and contraction is quite high. It is best to create a "frit" with silicone based paint (Like exhaust paint) if the bond is exposed through the acrylic / poly-carbonate . Have a look at most modern cars , fixed windows and you will get the idea. This stops UV exposure on the tape / sealant interface. Mask all except the frit area, lightly abraid with 180, and spray. Goop by itself can work on fiberglass boats and smaller windows but is not a good idea on other materials and definitely not steel boats. After sticking the windows in use a high modulus silicone and seal both inside and out. (This is why you use a silicone paint) Mask up all surfaces ...its quicker and neater in the long run because you can screed to the tape. (Clean prior to sticking tape with acetone or similar and dont touch the surface afterwards..even a finger print can badly affect the bond) Dont be tempted to put holes and fasteners in...if the job is done right it wont need them and they will only cause premature fails... I have done many windows and written a couple of how too articles...so far nobody has given me grief. Last lot of genuine 3M VHB I bought was $180 Aus. If you want the Aus price then buy it from Aus...most places dont care that much and will sell it to you. You may find it cheaper elsewhere on the net. A lot of our marine gear is double the price or more of the original companies home country in Aus...we are in the same situation as NZ in that respect so the strange and irrelevant rant about penal colonies wont help you buy cheaper... Getting stuff from the states is a different story, so much so, that you can employ the services of a buying and repackaging agent which will get you around inflated "home town monopoly's" on imported goods sold by exclusive agents. There are other brands that are the same stuff and a third of the price but you need to do your own research. Quote Link to post Share on other sites

idlerboat 116 Posted May 18, 2017 Share Posted May 18, 2017 Hi cj..I will try and find a link.. One was published in the American "metal boat building society magazine" .. I am no longer a member because they wanted to charge me to access my own intellectual property. Another....Metal boat building. org the free website that a few of us ran has now folded... I am in Townsville at the moment working on a boat but when I get back home I will try and find the original pdf,s..as well.. Quote Link to post Share on other sites
