Hi, does anyone know what type of plastic a Mk1 bumper is made from? I want to buy some glue to do a quick fix but it’s not clear to me what type of glue I’d need.
Cheers in advance.
If you are wanting to glue something to the bumper you can use A two part resin glue like Araldite but you will have to roughen up the area that you will be putting the Resin Glue onto to get a clean rough surface. Try it on the inside or underside of the bumper where it can’t be seen if you want to see if it works effectively. A lot depends on what it is you are trying to glue to the bumper.
A bit more info in your question would be good.
I have a UK spec MX5 with the rear fog cut into the bumper. My experiment is to see if I can fill the hole with a piece of bumper cut from an old broken one so it’s not a repair as I’d suggested but assume the right glue for the particular plastic is the right glue to use.
So where are you mounting the (mandatory since 01/04/1986) rear fog light?
The usual - convert the off-side reversing light with an appropriate red bulb
The best way to repair it would be by plastic welding, I’ve seen plastic motorcycle panels and plastic car bumpers done and the repaired area will still flex where a glued repair wouldn’t.
A plastic filler rod is melted t repair the crack as in this link.

I have done small repairs with a soldering iron, melting the two edges together to repair an item like in this link.

I repaired the front of the square hole above the exhaust with a soldering iron over six years ago before the bumper was painted. It’s still as good as the day it was done.
Glad it’s not the front bumper you want to do, I once tried to fill the holes left by number plate screws by melting new plastic with a soldering iron. I don’t know the material used but it resisted the soldering iron, approx temperature 450°C!
I’m a welder by trade, of metals that is.
I’ve just got to have a go at this.
The first link is brilliant; my lab technician did something very much like that at work nearly twenty years ago when fabricating some safety covers. The main problem is identifying the plastic. Now if their kit can do that…
The second video is showing such bad practice! That hot iron sticking up from the vice, just near his bare left elbow, nutter. He should use a proper soldering iron stand - they are cheap enough. I stopped watching that one after a few minutes.
^^^^^^^^^^^^^^^
I like life on the edge. It keeps the mind alert.
I’ve got to admit I only watched the first minute or so when he had the soldering iron in his hand, at that point he was showing how I’d done it.
Anything you do is at your own risk guys.
Stay safe.

Thanks for the responses. Of course I could buy a Eunos bumper without the hole without necessarily spending a fortune (anyone got a classic red one for sale?) but was looking to see what I might be able to achive. See photo of my first practice with an old scrap bumper.
