Plastic welding 3 Years, 4 Months ago  
Anyone here had occasion to have plastic welded?&nbsp; Would you recommend any local shops or suppliers of the materials?&nbsp; I remember a display from the Calgary bike show last year, but can&#039;t remember the outfit&#039;s name.&nbsp; I&#039;ve got a friend (really, its not me) who needs to fix a crack.<br /><br />

Re: Plastic welding 3 Years, 4 Months ago  
I know &quot;walleys bumper&quot; does it in town here. Pretty much any shop should be able to do it.<br /><br />What I do is get some of that mesh you can get at canadian tire. it is really sticky, and comes in a roll almost the size of gauze (I think). Put some of that on the rear of the fairing or the portion of the are you are trying to fix and put two part epoxy in the back. really stiffens it up, almost like fiberglass but Id hazzard a guess a whole lot stronger. Then simply go to an autobody shop and grab some plastic filler (usually comes in a blue bottle?) and spread it on the crack itself and sand it out. (id assume you are painting the product after?) If not, just leave the epoxy on the back so the crack wont get bigger. if you are good enough you shouldnt see the crack too much if you arent going to paint it up!<br /><br />I have found from experience without the reinforcement behind the crack is a lot more vulnerable to stress and will probably crack again, even with the plastic welding. With the supplies in hand, you are in a good position to fix many different stress cracks over time. <br /><br />At least thats what I do
