Greetings gents.  This is more of an overall opinion question.  I have been working a body off on my 80.  I'm getting close to body back on and then out to paint.  The rear spoiler has that waviness in it.  I know this happens to original spoilers.  The questions is, do I leave it this way for paint, try and fix it somehow, or go for a new unit.  The car is not totally original.  I know the NCRS guys would shoot me for removing original parts, but I want to drive this car and enjoy it.  Just wondering if anyone has any feedback or dealt with this situation before.  I see a lean towards tru-flex bumpers in past threads.  Any and all opinions are always a great help!  Thanks

 For what I have Noticed the 82's don't have as many Bends in them as the 80's and I doubt the NCRS can tell the Differnce. My 80 had them so Bad everybody thought they were suposed to be there.

You can't fix it...the only solution, if you want one with no waves is to go with the Tru-Flex type bumper(s)...
ALL urethane bumper covers will distort over time...there's no getting around it. The '80 cars were the first with the duck-tail rear cover...took GM a while to make them better, so, yeah, the later cars seem to hold up. It really depends on where the car is, geographically, and how much sun they get on a daily basis.
I put an NOS front cover on the '74 in '97, it stays in the garage 99% of the time, and it has started to get wavy already.
As far as NCRS goes...it's your car, and you can do what ya want with it.
( We're intelligent enough to know that the urethane covers have waves in them...they were never straight to start with. )

Yep, I figured there wouldnt be a fix for this.  Just thought I would throw that out there.  You are totally right about not worrying about what others think I should do about original parts.  Funny actually, I really dont mind the waves .  I should know better anyway.  I asked for some advise replacing a floor pan on this car (1980) on the NCRS site.  Some guy told me to patch it up and sell it fast.  He said there are plenty of 1980's out there and to cut and run.  I was like, so I should stick a problem car on some first time vette buyer and ruin his experience?  Never got a reply.  I only asked for some info.  The car had one bad spot on the passenger side, that was it.  My feeling is that all vettes, no matter what year are worth saving.  Got on a rant there......Thanks for the replies gents!

I think the look of the factory spoiler  even with the waves gives a C3 great character!  I like them so much that I spent a year searching for mine!!! Finally got a nice one and I love it!!

Switched mine to glass front and rear.  Love it!  It really makes the look.  It took my paint guy some time to work them in, the front longer than the back, but I believe it was well worth it.

AAA dropped it, front and rear, so I had to do something.  I also went with the one thing I've always loved on vettes that I otherwise would never be able to afford.  A C2 Stinger.

REMEMBER: You have to watch even closer at how far away from CONCRETE you park her.

I have a 79 with a factory 78 indy rear spoiler ... fit is terrible has one large "lump" that normally is on the left side BUT when at a car show sitting in the sun that lump will slowly move to the right side... 

Kind of Save the Wave tyoe of thing as far as I am concerned...

I don't pay too much attention to the ncrs crowd. I'm trying to work through the same thing though, my uretahne bumpers are shedding paint and really need some TLC. I know if they stay on the car theyre going to be the first trouble spots when I do get it repainted, so I'm looking at the trueflex bumpers. I like the look better anyways, especially when they get glassed into the body.

I know my rear spoiler is prolly different but its straight from the factory and has more waves then the Pacific Ocean   You might even be able to surf on it.  I tend to ignore it, I kinda like it, its original.  I say if yours is original, and you don't mind it, leave it alone

At a local Corvette event last fall, a 76 with 80+ style rear glassed in got lots of attention - very nice, very clean.  Now every time I look at a urethane bumper car, I think back to how slick that red 76 looked with the glassed in bumper covers.  I'd vote for that.
