finally found a rear spoiler. haven't seen it,but he sez it not broke but is separating? has anyone heard of that and is it fixable?

 

Yes and yes.

 

Should be. Does he mean the "clamshell" is opening at the seams? They do that sometimes, not a HUGE deal I don't think. IDK, somebody may have a smarter way to do it, but if there are no cracks I'd hit it with super strong epoxy. Body guys might know a better product, but that's what I'd to. But watch out when you handle it. Those things are as fragile as eggshells when they get some age on them.

 

The 91-92 spoiler is mostly fiberglass with plastic insert molded into the bottom. The mounting inserts are in the plastic part. If the two are seperating it's not a big deal to epoxy them back together. If there has been damage from being forced apart, by monkeys or freezing water, may have to seperate completely and fix the damage first, then reglue.
So, yes, unlike the earlier 85-90 wrap wings almost anything on the 91-92 wings is fixable.
Post up some pics and I'll tell you exactly how to do it.

 

x2. If it needs repair and painting anyways, just buy a repro. I had mine fixed up and painted only to have it shatter on installation.

 

Yip. I had to repair a crack in mine, and broke the tips off when I was trying to remove it. So I had to add gluing the tips back on to my repairs. Those stupid hooks they're mounted to are impossible.

 

It takes a special glue to fix the 91-2 plastic wing properly.

 

Yes to repair the plastic part you use that, but to rebond it to the fiberglass part if the two parts are seperating regular epoxy resin would be better but both side must be prepped properly.

 

Its all plastic. I have several that are completely shattered. You must have had a aftermarket one.

 

Sure it wasn't chopper gun made fiberglass? I'd swear the one I repaired was original, don't think they had repros then. I remember seeing fiber reinforcement inside of it. I may be misremembering, but I would have thought that plastic wasn't strong enough enough for GM to make a whole wing of it. I guess that would explain the shattering reports though.
I lost my pics, anyone have pics of one in peices?

 

No fibers in the plastic at all. I have one in the garage attic but im old, fat and lazy. Plus its cooold and windy here today or i'd take some pix 4 ya. lol

 

I used two part epoxy, 5000 lb strength on mine, but I'm not totally satisfied. On a couple spots where I used smaller amounts of glue it separated again after being exposed to temp changes over summer/winter, and I had to re-glue. I want a repro, but can't shell out the $400 for it just now.

 

The glue I posted about is pricey and uses a special gun but it works wonders on the xenoy plastic

 

Interesting. Guess the guy I sold one to got a better deal than I thought if it was a repro.

 

I just picked up an aero spoiler that needs repairing. Two attach points need reglued, and a crack on the top side. Has there been any new epoxys since this thread was active?

 

Just use the stuff from my post #7 above. Its made for this xenoy plastic.

 

thanks

 

Before I buy it, is there a way to apply without buying the special gun also?

 

Just squeeze out equal parts and make sure its mixed very well. That's kinda what the gun and nozzle does.

 

If you Google, or even just search Ebay with the 3M number for the special applicator gun, usually there's a Made in China, "Harbor Freight" grade, substitute available. The specific 3M tool might be $100 while the knockoff does the same thing for $20. You can also find dealers with old stock of 3M applicators they'll sell for realistic prices just to get them off the shelves.
