Hello,Between structure jobs and others thing I begin to cover the rudder and the stabilizerto practice and learn about the covering process. I bought a book fromPoly-Fiber, read an other one from the 70's wich talk about all the differentstechnics (even fiberglass..), and after all and with the resources I have Idecide to coverit with Dacron fabric and polytak. It is easy, and the finall result is excelent. But.. I had a big problem... I cannot find Poly-Tak in my country, buy it in Aircraftspruce it is a possibility,but cost USS 300 the delivery cost because it is a "dangerous product".. Ibought a qt in Argentina, very expensive, few months ago, so I use Poly tak justfor the borders joins, all the other jobs like the reinforced tapes I useconctact cement, and as I can saw it work perfect, the only problem I found isthat you have just one opportunuty to do the job, you can not make adjusts, sosome little wrinkles in the curved parts result.Why nobody use contact cement?, I am talking about the one based on toluol, theone you have to brush both surfaces, wait some minutes and join them... It isvery strong as I can see, with care is easy to apply, is cheep, but I can imaginethat in big fabric pieces could be difficult ti apply. Is there anotherreason because nobody use it it?regards.Mario--------Mario Giacummohttp://vgmk1.blogspot.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Mario,Two questions you may ask (well, there are lots of questions, like: Is itflammable?), but two that come to mind are:1) How does UV affect contact cement?2) What holding power does it have at 100 knots? 150 knots?You may never find the answer to those questions, because; A) it's neverbeen tested, B) it performed so badly that it's not a good consideration.I have used Polytak and have nothing bad to say about it. Given yourshipping issues, though, you may want to take a look at Stewart SystemsEko-bond. That's what I used this time around and it is very easy to workwith! It's a zero VOC product and you should have an easier time withshipping.Gary BootheNX308MB-----Original Message-----

Why perform badly?.. not talk about UV, what are the others reasons?I make some home test with dacron, contact cement, wood, and dacron, polytak, wood,and the contact cement example was too much stronger in peel off and sheerthan the polytak one; may be we are talking about differnts adhesives or maybe it perform bad over the time? I like the polytak, it is a matter of priceand disponibility, nothing else.--------Mario Giacummohttp://vgmk1.blogspot.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Fri, 11 May 2012 16:10:33 -0700 (PDT)
