miles.gray Posted April 21, 2019 Share Posted April 21, 2019 What is the easiest way and best glue to use to reattach front mudguard. Only the rear one has come unstuck. Thanks. Link to comment Share on other sites More sharing options...

SM25T Posted April 21, 2019 Share Posted April 21, 2019 You might find powder coat has come off stay. If so, clean stay and paint to seal it. You need to clean underside of wing with acetone, or meths if nothing else available. Rebond it with Sikaflex or Tigerseal. Fillet either side of stay. Run three lengthways strips around the inside of the wing and up and over each stay like hump back bridges. Don't drive it until it has completely cured.

ScottR400D Posted April 21, 2019 Share Posted April 21, 2019 The easiest way? Put two bolts through. Link to comment Share on other sites More sharing options...
miles.gray Posted April 21, 2019 Author Share Posted April 21, 2019 thanks, another stupid question (s) do the wingstays have to be removed? If so, I can't see how the indicator wire gets disconnected. Looks like quite an involved job getting wing stays off. I'd rather not drill them if poss (I even though it would mean I can drive it this afternoon... Link to comment Share on other sites More sharing options...
SM25T Posted April 21, 2019 Share Posted April 21, 2019 Don't need to remove the stays. Remove the wheel for access. Link to comment Share on other sites More sharing options...

ScottR400D Posted April 21, 2019 Share Posted April 21, 2019 No, no need to remove, it would be hard to see what advantage that would give even on a first fit. I don’t think drilling is a bad thing, actually. Especially if you’re going to effect the repair with the front part of the stay still attached. Cleaning off the old adhesive and redoing won’t be easy. I used studded big heads bonded to the front part, and fitted through holes in the stay, with two bolts through the rear. Black bolts on carbon wings. I never notice those bolts, being quite low and no-one’s ever mentioned them, they’re quite unobtrusive. I guess coloured wings give you less chance to make it unobtrusive. Link to comment Share on other sites More sharing options...
Area Representative Geoff Brown Posted April 21, 2019 Area Representative Share Posted April 21, 2019 To repaint the wing stay would create a surface that will create a poor bond with the adhesive.Best to leave a narrow strip of bare degreased metal along the top of the stay that will be covered by the adhesive fillet. Then there is no chance of corrosion occurring. To ensure a good key lightly score the bare metal cross hatch using the edge of a three square file (triangular). Ensure that the opposing surface on the wing is also lightly roughed up with 120 grit & cleaned.This preparation should ensure a long life for the wings. My last Seven is still going strong 18 years later with the same wings, same careful preparation & Tiger adhesive............. Link to comment Share on other sites More sharing options...
ScottR400D Posted April 21, 2019 Share Posted April 21, 2019 Geoff, can you actually do that with the wing, presumably, still stuck on the front part of the stay? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted April 21, 2019 Member Share Posted April 21, 2019 I wouldn't. One of the points of attachment has already failed. I'd strip down the other to be sure that the preparation (as above) and fixing were done properly....There's a vast amount on this in the archives, both with methods that only use adhesive and those that use mechanical fasteners. I suspect that failures when only adhesive was used are more likely to have been caused by poor preparation rather than the wrong adhesive. And I prefer a sausage roll to humpback bridges or a sandwich. NB If you choose "Sikaflex" there are a lot of different Sikaflex adhesives (and sealants!).Jonathan Link to comment Share on other sites More sharing options...
Area Representative Geoff Brown Posted April 22, 2019 Area Representative Share Posted April 22, 2019 I would strongly advise totally 'unsticking' the wing as the remaining attached point would have been under some stress & therefore the bond could have been weakened.Starting afresh guarantees that the wing will remain in place!JK - You are 100% correct - good preparation is as important as the finished article.

miles.gray Posted April 22, 2019 Author Share Posted April 22, 2019 Thanks again. I've reattached and have a liberal spreading of tiger seal on the wings, wing-stays, my drive, my hands and even in my hair! I did give the wings and stays a good clean so fingers crossed.
