Inside rear wing protection

[Toby S]

I've just bought a second had pair of rear wings in great condition

My 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

Isoflex rubber roof sealer from B & Q etc few coats with a small foam roller, greatly reduces the star cracks

Thanks 7WOTW

Jonathan 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

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.

Camping mat glued to the inside. 10 years and no sign of damage.

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.

Wings stays used to come in 2 sizes - 13/14" and 15/16"

and there 2 sizes of 13"

'standard' for 185/70x13        and 'race' for the 175/55x13 (fit 185/60x13 too)

for standard are used for the 185/60x14 too

Just replaced all four wings and used this:

'Paint' it on very thickly, lots of fumes so do it outside but leaves a thick soft coat that will absorb hits from stones.

I have used 'Flashing" on two cars, sounds agricultural but it works and just needs a small

heat up and a press fit. two cars no cracks

[Toby S]

Thanks guys - a few options to think about

I used a couple of coats of Stoneguard.

+1 for Paul Richard's suggestion #5 - now 8 years on and works well.

[SLR No.77]

Paul's suggestion also adds very little weight ...!

When I read this I had a vision of you bonding a role of Code 6 lead inside your arches.......

I was worried about putting my head above the parapet with Flashing...hey its light, flexible and proven and so easy to fit
