hoobby Posted August 4, 2021 Author Share Posted August 4, 2021 (edited) The bulges do reduce a lot in size (see pics) so had to dig more foam out going to use tape to pull these areas straight when I bond the frame back in.

As these frames rust they leach into the foam and make it expand. Edited August 4, 2021 by hoobby Pics Quote Link to comment Share on other sites More sharing options...

1200bandit Posted August 13, 2021 Share Posted August 13, 2021 Have a slight bulge on one of mine Thinking if l used a hole cuter to remove the stud ,then use a stainless steel captive nut ( bounded into the trim) then use a stainless bolts Make the securing holes a bit bigger for adjusting Quote Link to comment Share on other sites More sharing options...

hoobby Posted November 25, 2022 Author Share Posted November 25, 2022 Well it's been over a year since I started the repair on the spoiler fins problem 1 the replacement frames tho exactly same dimensions as old ones will not fit back in the spoiler so will have to remove more foam thus losing the alignment will have to fit the frames while fitted to the car using the rear spoiler to line up. Problem 2 boot will never sit where it should due to the badly damaged n/s hinge but thanks to Vince have got a replacement in fantastic condition. Problem 3 main rear spoiler bulging badly at fixing points so will stop the boot closing or push the fins out creating a horrible gap this one I'm really not looking forward to doing have been wire brushing and spraying with aerokroil so far three of the nuts are moving so if I can get away not shearing any of these off and the fixings are not too rotten will just dig out enough foam to get the bulges out treat the rust,paint and refill with tiger seal....well that's the plan.

Jessopia74 Posted November 25, 2022 Share Posted November 25, 2022 There are fibreglass options for spoiler if the repair is not possible. Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted November 26, 2022 Share Posted November 26, 2022 having not had a car with this type of spoiler i assume its the same issue as occurs on the rubber overiders on chrome bumpers. the metal inside the rubber rusts and swells and the mounting stud falls off.you end up with a crumbly mess ! 1 Quote Link to comment Share on other sites More sharing options...

Pretty much mate, yes. They are just a stud on a larger head(washer/hex, seem to be various styles but all are basically same thing). They are cast into the rubber, but over time as they are ferrous, water ,wicks up the sides and the starts the corrosion process. Same thing on the GTE hockey sticks too. Such a shame they did not use galvanised studs, but at the time if manufacture, life was ~10 years max. You can cut them out and rebound new ones back in. Need something like Sikaflex522 and a retained stud. https://www.hall-fast.com/bighead-mild-steel-male-threaded-studs-m6-x-50-213528 https://gbr.sika.com/en/industry/transportation/sealants/adhesive-sealants/sikaflex-522.html 1 Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted November 27, 2022 Share Posted November 27, 2022 yes thats what ive done to overriders in the past. drilled deepest absolute possible hole i could and then bonded a long stud into it. in years gone by the manufactures would have no doubt used a brass stud to stop rusting .! 2 Quote Link to comment Share on other sites More sharing options...
®evo03 Posted November 27, 2022 Share Posted November 27, 2022 Is there anything you can do to to the original fixing to protect from this happening, Eg, I have new unused overriders, never fitted, can I do anything with the original stud, obviously don't want to remove stud or disrupt over rider in any way.

Seal it when fitting to stop water going up the threads/getting behind the captive stud. 1 Quote Link to comment Share on other sites More sharing options...

All so use copper slip on the stud will stop the nut getting sized onto the studs 1 Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted November 28, 2022 Share Posted November 28, 2022 exactly. not sure of the internals of the spoiler but the overriders are rubber moulded over a metal frame which the stud attaches to internally. the rubber itself should be watertight ! so anything that you can do to stop water getting up the stud and on it should help.especially on a new one . p 2 Quote Link to comment Share on other sites More sharing options...
