Wavy Plastic Bumper Syndrome
#1

Ok this has been bugging me since I bought my car - and it's black so this is really easy to see:



By now most 968s I've seen have 'sagging' areas in the bumper covers that create wavy, unsightly reflections. I have two slightly depressed areas in the front bumper cover just below the front edge of the hood, and on the rear bumper cover the areas to the left and right of the key hole look a bit 'pushed in' as well, again causing wavy, really ugly looking reflections.



Has anyone devised a fix for this?



I was thinking maybe some foam added to the backside of the bumper covers in the affected areas might push them back out to where they should be so the surfaces are even again. Thoughts?

I think I know what you mean, I've seen the same thing on 944s. Do you have pics?

Harder to spot in light colored cars, but here's an example of the commonly affected areas:

Yup, same exact spots on the front of the 944 - not the same on the rear because of the different rear-end on them though.

With those wheels does it really matter? <img src="/forum/images/smilies/968/wink.gif" class="smilie" alt="" />

Lots of posts in the BMW, Miata and other forums on the same exact problem.

I want your wheels. On topic though, the front and rear covers are made from plastic. 944's are metal, except for the bumper cover itself. Not sure how you would get the warped waves out without bondo, or just replacing them. Have you had an experienced body shop look at it? Foam pads seem possibly feasible.

The wavy bumper (or is it the delaminating hatch glass) annoys me more than anything else. and yet... never tried to fix it. I once saw somewhere - who knows where - an article about modding a racing car and there was a picture of two aluminum angles - I believe perforated - epoxyed to the backside of a troublesome body panel to give it greater stiffness. I've always thought that solution might work for our wambly bumpers. I really don't know if that would work or not. But that would be where I'd start the conversation if I took it to an experienced body shop.

ha - I want your wheels, too!

it should be pretty easy to make up a web of straps that went from the upper grill to the mounting rail, and had a transverse median strap

I'm looking at a fantastic green cab that I'd love to buy -- it will put me into the 968 Club. 45.000 miles, always garage kept. But it suffers from both these sag areas.



I'd love some bright ideas. It would obviously affect my purchase maneuvering.



I remember seeing in one of the forums that someone had successfully gone after deformed 'A' pillar trim with a hair dryer. Any brave souls out there?

Which green cab, plittell? I've seen several up close and personal in MA, CT, and NY, and I might be able to compare notes with you before you buy.



According to the Miata forums, the sag saga is a constant variable and filling does no good - although epoxying a formed aluminum bar on the back side of the piece might help permanently and inexpensively?
