richy Posted July 22, 2012 Share Posted July 22, 2012 Either method appears to be popular - so long as it's done right. Plenty of threads on here regarding removal of powder-coat from wing stays, using big-heads&cable ties, or wrapping Sikaflex around the stays. Me - I've bolted them on, but wish I hadn't. Now have cracked wings around the bolt holes. ☹️ On the bright side - they'd have cracked anyway from stone chips Richy Link to comment Share on other sites More sharing options...
DJ. Posted July 22, 2012 Share Posted July 22, 2012 I've seen wings that were bonded on with crazing around the bond, so you can get that either way ☹️ I'm sure Caterham don't use bolts, because it is time consuming to do a neat job. Sikaflex works if it's done right, so do bolts. If you really want them to stay put, use glue and bolts 😬 Duncan Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted July 22, 2012 Area Representative Share Posted July 22, 2012 Master Thatcher, What is still stuck to what? Either way good preparation and materials is the answer. If the wing and stay are cleaned up, and the surfaces roughened, then a liberal spread of any PU adhesive/sealant is stronger and neater than screws. My wings have had some hammer, but I've never had a wing come off. Link to comment Share on other sites More sharing options...

Johnty Lyons Posted July 23, 2012 Share Posted July 23, 2012 I've had to restick a couple of Caterham factory stuck onesIts a case of the 7 Ps IMHO Once properly stuck they are there for life Link to comment Share on other sites More sharing options...
Area Representative Nick Chan Posted July 23, 2012 Area Representative Share Posted July 23, 2012 Quoting Richard Price: My wings have had some hammer, but I've never had a wing come off. Is that what they call a big orange cone now! 😬 I agree that done properly, mastic works very well. The only time we have had a wing come off was a) when the hard as nails stuff used before our ownership factured and split (and was replaced successfully with mastic) and b) when the wing stay sheared - although the mastic still did its job and the wing was technically still attached to the stay 😬 Nick Link to comment Share on other sites More sharing options...
myothercarsa2cv Posted July 23, 2012 Share Posted July 23, 2012 I'm bolted. Don't suppose they are ever coming off now... Some crazing and small cracks, but mostly from me walking in to them! I'd glue next time, simply because it's easier to get off! Link to comment Share on other sites More sharing options...

Member Jonathan Kay Posted July 23, 2012 Member Share Posted July 23, 2012 Thanks. If it's Sikaflex wrapped all around the stay which bit failed? Did the tube of Sikaflex rupture? Jonathan Link to comment Share on other sites More sharing options...

Jonathan Looks like the sika failed where it was epoxyed onto the fender, couldbe that the surface was'nt clean or not scored for a good bond, Think I might rivet them on, as I have a friend who assures me using a complex of gromets and fasteners he can do a great job without causing any spyder cracks or chips, he works for Bentley Motors down the road!

Member Jonathan Kay Posted July 23, 2012 Member Share Posted July 23, 2012 Thanks. So the tube of Sikaflex stayed intact and held it on loosely after the adhesion failure? Jonathan Link to comment Share on other sites More sharing options...

Jonathan Looks that way, the area on the fender looks completly clean as it's just not adhered to it properly Link to comment Share on other sites More sharing options...

Smiffy69 Posted July 26, 2012 Share Posted July 26, 2012 I've bolted mine on but used rubber grommets on the top side between the bolt head and wing and a strip of sticky padding on the underside to act as an insulator to vibrations. No visible cracking to date so fingers crossed! Link to comment Share on other sites More sharing options...
