Best glue for rubberised plastic indicator?
« on: June 30, 2024, 07:39:19 AM »
I am wanting to do a tidying job on a 1998 CB500 twin. As a temporary fix I want to try gluing a broken indicator stalk. They are a rubberised plastic construction designed to flex and not easily break. With age I think they are now somewhat brittle. Looking to sell the bike and although I will be honest about the fix it will make images look a lot better!

Appreciate any suggestions of best glue please?
One day I'll have the time to restore it, not just talk and dream....

I have used Tiger Seal to re-attach suspension bump stop rubbers to steel - I had a Nissan with huge bump stop rubbers inside the rear coil springs. I also attached a rear taigate handle to a boot lid with the adhesive after holding the item in place with masking tape leaving the tail gate open until it set.

I was given a part tube by a local bodyshop who use it to re-attach the front wing on some Audis that are made of a type of plastic. It bonds the wings to the steel inner panels

It is usually black but other colours are availabe - downside is once the tube has been pierced it will go solid in a week. You also have  to hold the part in place until it has set - 24 hours until its set in warm weather.

Not sure of the shape of your stalk but it would be stronger if you could fit an external sleeve over the joint.

Cheers Ted. Hadn't thought of it. Used it before actually - sticks like s--t to a blanket! Holding in place with tape etc would not be an issue wouldn't think. Just a cosmetic job as I say so want to avoid additional bracing.

There are superglues designed for rubber. I have repaired quite a few rubber boots and suchlike using this stuff. Will post product details if you want.

I think I bought my last lot from Westfield Fasteners.
I have found you can lightly sand down any 'drips' once cured and it gives an almost invisible repair.

Interesting thread, always good to hear what other's are using.

This may be of help https://www.permabond.com/resource-center/rubber-bonding-type-rubber-unknown/ I've not used this or the previous suggestions, so curious as to outcome.

Have tried to repair or revive indicator stalks before, with notable and probably 100% failure  :) the rubber does appear to loose it's properties and not ultimately absorb adhesive when it gets harder though.
