noobiemcnooberson. Posted May 5, 2010 Report Share Posted May 5, 2010 just get a soldering iron, the same type of plastic and remove any paint on the surfaces you are trying to join. make a v between the two surfaces and fill it in. super easy. its how i fixed my bike.

copperhead Posted May 6, 2010 Report Share Posted May 6, 2010 Jason, i've done this a lot. i've told you i'll fix the shit for you, just cover the cost of supplies and i'll get it all ready for paint Quote Link to comment Share on other sites More sharing options...
Clifford Automotive Posted May 6, 2010 Report Share Posted May 6, 2010 Whoever says plastic welding is junk, doesnt know how to do it. Or just simply can't. Sorry Hobs. I spent 5 years training employees of Keystone Automotive how to weld all types of plastic. And when the weld was done, it was stronger then the rest of the surrounding area. That is a fact. I helped write a book on this shit. If you want some help, I can help you. I do it about once a week now on covers that are cracked for delearships. And if you go through and look at my last few covers from board members you will see that backsides of those are welded to fill the license plate holes. Welds will last forever on the plastics, fillers, 2 part expoys, etc, will not. Quote Link to comment Share on other sites More sharing options...
88lx5oh Posted May 6, 2010 Report Share Posted May 6, 2010 im glad you wrote the book on plastic welding.. thats great, may work great on bumpers on bike plastics i dont trust it, its brittle, ive seen it done before, and i have seen it fail before i worked at a shop where all i did was fix busted up bike fairings all day.. i used Plastex exclusively.. and i still use it to this day if you have never used it you wouldnt understand. this stuff is better than anything on the market for motorcycle fairings period. i dont sell it, im not making money off telling people about it.... it just plain works, and works very very well.. again its the best shit out there plain and simple. kevin pick some up and try it on a motorcycle fairing.. youll be highly impressed with the results. again jason.. if you want to get those fixed buy some plastex and do it right... seriously use it. Mike has used that stuff to. there is a thread on OR where someone was looking for somethign to fix a broken headlight on a zx600.. i lead him to the plastex and he had nothign but great reviews about it. i have some left over sitting here if you wanna try it first. .. but again.. you wont be disappointed in the results hell i used it to join a 3 piece tail section on a cbr f2// made it a one piece tail... you could bend and flex it with no issue.. the plastex was stronger than the oem plastic they use..

88lx5oh Posted May 6, 2010 Report Share Posted May 6, 2010 Welds will last forever on the plastics, fillers, 2 part expoys, etc, will not. plastex isnt a filler, or 2 part epoxy do some research its a 2 part chemical.. put not an epoxy it uses a chemical that actually eats and bonds into plastic then uses a powder form of plastic that fills and bonds with the oem plastic. its a more effective way of plastic welding persay it chemically bonds instead of heating and melting if you heat plastic it makes it brittle known fact Quote Link to comment Share on other sites More sharing options...

88lx5oh Posted May 6, 2010 Report Share Posted May 6, 2010 Is it avilable locally? nope.. online only.. doesnt take long to get it though.. well unless cycle search has some.. i know they stocked it a while back.. call and ask Quote Link to comment Share on other sites More sharing options...
88lx5oh Posted May 6, 2010 Report Share Posted May 6, 2010 ill show you how to use the stuff to.. but it does come with a tutorial dvd. its fairly simple to use though they even give you some moding pieces that way if you have a broken tab, you can use the molding blocks around a tab that is similar and make a new piece out of the plastex for the missing/broken tab Quote Link to comment Share on other sites More sharing options...
C-Mart Posted May 6, 2010 Report Share Posted May 6, 2010 if you heat plastic it makes it brittle known fact +1 once you heat plastic it will never be as strong. It has to do with the chemical bonds that is why "plastic welding" has always made me laugh Quote Link to comment Share on other sites More sharing options...
smokinHawk1647545499 Posted May 6, 2010 Report Share Posted May 6, 2010 i have done plastic welding with a soldering iron on a ninja faring and a yamaha fairing, worked and held fine. Quote Link to comment Share on other sites More sharing options...
TurboNova Posted May 6, 2010 Report Share Posted May 6, 2010 Donnie at bob boyd does some of the best work I have seen, I wholesaler that works the area buys alot of crash bikes and brings him the plastic along with the cracked pieces and he welds them and paints them then throws the decals on them... seen alot of wrecked bikes and he does some awesome work.

Clifford Automotive Posted May 6, 2010 Report Share Posted May 6, 2010 I know its not an epoxy. Only giving examples above of inferior repairs. Urethane Bumper Covers, TPO Bumpers Covers, ABS Parts, are not made out of the same material, that would get britle upon heating like you guys are refering to. Totally different. #1 Reason being there is a percentage of wax in the molding mixture. This is what allows types of plastic to flex (bumper covers) When you heat wax it only becomes more pliable. When you cool wax then it become britle. If you have a large dent in the side of a bumper cover, it gets heated and the dent will pop out. Plastic has memory. There will be an edge but it comes out. It doesnt break. More covers are cracked in the winter time then in the summer time. There is a reason for that. I've used platex, and every other type of plastic repair material. There is nothing out there that will meet the quality repair of thermally welding platic. Nothing. I worked on a corporate board testing all these material against each other. Not just this, but many more types of fillers, adhesion promotors, etc. All of the research we perform is not set as a standard for platic repair across the united states. Its accepted as the #1 repair with ALL insurance companies in the industry. Quote Link to comment Share on other sites More sharing options...
copperhead Posted May 6, 2010 Report Share Posted May 6, 2010 Is it avilable locally? I've seen it at Harbor Freight. If I can, I'll head over there tonight to pick some up for ya. edit - nevermind, they close in 10 minutes. Quote Link to comment Share on other sites More sharing options...
35RFTW Posted May 7, 2010 Report Share Posted May 7, 2010 Plastex is available locally @ Cycle Search. We can even ship for those who are too far away. FWIW, I have done both numerous times and I would rather weld than chemically bond. Also the plastex will not sand down like surrounding plastic and can create an uneven surface if you are not careful. Quote Link to comment Share on other sites More sharing options...

One thing I forgot to add, is when doing a thermal weld, your welding with a Rod that is made out of the same material your welding. This is why it 100% works, your not mixing material. I have welded many bike fairing in the past 10 years, and I have yet to see one crack again where it was welded. And to top it, I can be finish sanding the front side, while we are waiting around on the back side to cure using other methods of repairs. Hobs I believe you have used this material exclusively. I wont argue that. Quote Link to comment Share on other sites More sharing options...

Tractor Posted May 8, 2010 Report Share Posted May 8, 2010 I weld plastic on things all the time at work. 99% of the time it holds good as new. Sometimes its just in a place where your not gonna be able to make it work or its high temp plastic which I haven't managed to get to stick very often.
