Thanks Dave. And, as Odd pointed out, these are the North American bumpers,

not the rest of world ones. Ours our covered with something different, Bayflex

90, a thick flexible plastic which has held up remarkably well over the years.

Plus, we thought it could be sanded down and polished (just like any plastic)

and made just like new with only a little bit of effort and the cover was

thick enough to tolerate lots of polishing. Might still be true, except in my

case where it might be that someone did a plastic bumper repair I never knew


I would like to confirm that the Bayflex stuff IS black through and through

though. I've crawled under the car and looked at the backside of some of it

(where it's bolted to the bottom of the bumper frame). I was beginning to

doubt myself since folks on the Facebook page claim they've seen orange/tan

underneath after sanding. As I said, I have my doubts but, I've been wrong

LOTS of times. :-)

So, if aggressive sanding of a bumper cover material starts showing another

color, we (TWOA) should stop recommending the sanding treatment!

Of note, Harris Mann wanted the bumpers BODY COLOUR but it was amazingly

difficult to get any paint to stick to the Bayflex back in his day. It's good

stuff. Nowadays, we can find paints and the like to stick to it and lots of

people paint their bumpers. Like Dave...

Maybe someone painted them and used a primer.B  Perhaps some minor accident


During the restoration I repainted my bumpers and used a special paint and

primer for rubber bumpers.B  The primer was white (grey?) and showed through

where ever there was a scratch or ding.B  I regretted painting them and will

just sand down bumpers from now on.

Yes, I do.B  I have so many that I was considering dissecting one to

illustrate how the pivot pin determines the front bumper angle.B  I'll be sure

to select one I didn't paint previously.

Wedge List / an old scrap bumper?
« Last post by tencate on September 05, 2019, 08:02:55 PM »
does anyone have an old scrap bumper sitting around that was destined for the

trash heap someday? If so, can you take a sanding disk to it and see if you

can find a colour underneath, presumably white? If so, take a few photos and

send them to me? I'm clearly working on a newsletter article based on my

recent bumper experience...

Bayflex 90 (the stuff our bumpers are covered with) was black through and

through. Or so I've always thought. That means you can polish, even sand with

impunity and not worry about taking off too much black coating. It's all

black. Or is it?

Well, I was cleaning up some heavily oxidized parts of my rear bumper using

400 grit and a sanding sponge and I'm now seeing white showing through at the

high places.


Anyone ever seen that before? Not sure what to do either, paint that section

of the bumper? It's just one small piece of the bumper, no hint of anything

odd elsewhere, it's just coming up WHITE underneath on the drivers side rear.

Photo on TWOA's Facebook page in a few minutes.

ACK. Just before Triumphest too.

Any thoughts? Keep sanding and hope it's just a coat of something???

Be sure to check the orientation of the terminals to make sure the leads will reach the battery terminals and allow for a disconnect switch on the negative terminal.
