Is it possible to save the rear spoiler and mirror rubber on a 924 turbo? The spoiler is intact but shows signs of really bad wear. Pitted and looking like someone took a sand blaster to it. Same with the mirrors. Can this be repaired? Any pics on how the spoiler/mirrors are suposed to look up close? Thanks.

I have the same problem with my 81. I tried a conditioner (Turtle Wax Wet N Black). It helped the looks but it contains silicone which is still leaching out on to my new paint. The mirror surrounds can be replaced with part number 911 731 041 00. BTW the rubber surrounds will work on either side. If the bottoms aren't pitted you could rotate them and have the good side up. Not sure if the spoiler is still available.

Here's my rear spoiler now. It's flat matte looking all over with an assortment of tiny holes at the leading edge. Not wonderful, but not terrible either - It looks way better after treatment with conditioner. If it were bothering me, I might experiment with some of that Tire Black stuff that you paint on. That might fill in the holes and smooth out the surface, but the stuff might just flake off over time. I'm happy to just douse it with conditioner whenever the spirit moves me.

I use some of that wet look stuff for your tires it gives it a nice look use it on the mirror surrounds also.

your spoiler looks to be in much better condition than mine Smoothie, mine is quite pitted and a lot of the smooth surface has gone.. mine also looks like someone has tried painting it with black paint in the past.
I went over it with a conditioner and gave it a few coats, but the paint marks are still visible.. i'm not sure the paint protected it any.

are there ways to recondition them?
(maybe using gaffer tape and expanding foam? that seems popular!

)

Mine looks like a used heat shield from the shuttle but it is all black. I have been trying to figure out what could fill the pitts but nothing reasonable comes to mind. I have considered black RTV but that would be a one chance thing. If it worked good it would be great but if it didn't I would be looking for a spoiler. I also thought about that "DipIT" stuff for tool handles. It comes in black and is a rubber paint ... but how to get it applied smooth?? I am baout ready to go buy a hatch from the yard to experiment with.

i'm not familiar with the rubber stuff you mention Sleykin, but it sounds as if you could perhaps over-fill the holes and then cut the surface smooth with a knife perhaps? or some vary careful sanding if it's a bit stiffer?

that might work for some small holes, but for larger areas of degradation it might be easier to work some overtime and just buy one.

I don't know where you would find it in OZ but you can get it here in Ace hardware.
My ovetime rate is only $60 an hour so it would take a bit to buy one new. All the used ones I have seen are in the same shape so... The option of buying a rear hatch from the yard and playing with the rubber spoiler is looking good as I need to re-attach my glass to the frame now. I bought new hatch shocks and of course that ripped the seals on the glass to frame bond. No leaks but I get that nasty chitter-chitter from the back that makes it sound like a Chevett at times. Only bugger about that is I just payed $250 to have the windows tinted. Fellow that did the tint said it was a right bi*%h to do the back glass.

$60 an hour.. well, I get paid a bit more than that per day, but...

i'll be curious to see how you go..
damn these forums - other people asking stuff just makes my to-do list longer!

would body filler work?maybe use the body filler sand it back down smooth and paint it like fiberglass or plastic spoilers.

I have some experience with tool handle rubber coating and I'm pretty sure it's not the way to go for restoring the rubber spoilers. The stuff I used seemed to be lacquer based and skinned over or dried on the surface very quickly, while underneath, it took longer to dry. Based on the way the stuff behaves, I think I can predict that you'll end up with a gloppy mess as the stuff dries while you're spreading it on.
Regular body filler doesn't seem too appealing either. Maybe a flexible body filler in black if such a thing exists (it should exist for flexible bumper parts and the like, but whether it's available in black...).

I just doused my rear spoiler today in some Speedy something-or-other silicone treatment, so I won't be experimenting on it any time soon, but I might try the Tire Black paint-on stuff on the mirrors' rubber parts. I'll let yous know how that goes.

Here's the rear spoiler after treatment. Click little pic... -

...and the Speedy stuff -

My spoiler looks like heck compared to yours Smoothie. I'll try some of that stuff you use on yours but I doubt it will help mine that much, unless that stuff can fill pits! Thanks for the tip though. Might work well on my mirrors.

Yeah Smoothie ... fear of a gloppy mess is what has kept me from trying it. There has to be a good way to re-new it though. I am going on a PCNA poker run this weekend to try out the club and see if I want to play that game for awhile. Perhaps some of those folk have a solution. I will let ya'll know if I come up with something.

Autoglym Bumper Care brought mine up a treat, but there's a few holes appearing on the inner edge. Does nobody like the 968 style ones?

I did some experimenting on some old tires that had badly weathered and cracked sidewalls. I used a cheap $4 aerosol can of rubberized undercoating - sprayed it on, then brushed it in, then sprayed another light coat on top. I'd rate the result "marginal" - you're left with a somewhat brown tinted, brush-textured finish. Might make a good cheap-easy improvement to a spoiler that's in really really bad shape, but there's got to be a better solution. I played a bit with "Tire Black" also, but that stuff's thin as dye, so it's useless in filling cracks. It might be usefull over top of the undercoating though, in case the undercoating needs to be darkened.
