Toby S Posted June 15, 2020 Share Posted June 15, 2020 I've just bought a second had pair of rear wings in great conditionMy old ones are in very poor state with star cracks all over the place, loads of splits, cracks and the gel coat on the outside (shiny side) cracked and lifting in a number of places. In the main the damage has occurred due to stones off the R888R's being thrown up and hitting the inside of the arch as opposed to debris hits on the outside (although I did have a pheasant strike recently - had the brooklands on so it could have been worse).I was wondering what people do to protect the inside of the wings. I've thought of:- Strengthening the wing with additional layers of fibre glass and epoxy on the inside Glueing layers of a cut down truck inner tube to the inside of the arch to give a rubber layer of padding (not sure which glue I'd use though) WaxOyling the inside.Was wondering if anyone had any recommendations, do and don'ts Link to comment Share on other sites More sharing options...
7 wonders of the world Posted June 15, 2020 Share Posted June 15, 2020 Isoflex rubber roof sealer from B & Q etc few coats with a small foam roller, greatly reduces the star crackshttps://www.google.com/search?q=isoflex+liquid+rubber&rlz=1C1GCEA_enGB772GB772&oq=isoflex+rubber&aqs=chrome.6.69i57j0l7.13596j0j7&sourceid=chrome&ie=UTF-8 Link to comment Share on other sites More sharing options...
Toby S Posted June 15, 2020 Author Share Posted June 15, 2020 Thanks 7WOTWJonathan also sent me a PM and suggested the same - looks like just the job - should be an easy job to do before I put the the new wings on the car.Might also do the front ones, whilst I have the paint brush handy before they get any worse Link to comment Share on other sites More sharing options...
TomB Posted June 15, 2020 Share Posted June 15, 2020 I put a couple of coats of Waxoil underseal stuff. Apparently not great, but I only found out after I’d put two coats on! The perfect product would be a carbon fibre wing lining that you could bond in. Link to comment Share on other sites More sharing options...

L777JDP Posted June 17, 2020 Share Posted June 17, 2020 I've just use Dry Base, which is a water based plastic polymer, used under plaster to stop damp coming through walls, to waterproof the inside of some planters. It sticks well and can be applied quite thickly, and dries quickly.This topic has just become relevant to me as I have my first star crack on a front cycle wing. I've recently moved to 13" Apollos with ZZS tyres, so perhaps the extra space gives the stones time to pick up radial velocity before hitting the inside of the wing.I don't think there are wing stays specifically for 13" wheels, but something I intend to check on.

NeilCSR Posted June 18, 2020 Share Posted June 18, 2020 Just replaced all four wings and used this:https://www.carbuilder.com/uk/wunderseal-underbody-sealer'Paint' it on very thickly, lots of fumes so do it outside but leaves a thick soft coat that will absorb hits from stones.

Alan Reeves Posted June 18, 2020 Share Posted June 18, 2020 I have used 'Flashing" on two cars, sounds agricultural but it works and just needs a smallheat up and a press fit. two cars no cracks Link to comment Share on other sites More sharing options...
