I need to repair or replace the rear heating element of my Disco.

I found this stuff, Granville Rear Heater Repair on the Halfords website.

However most of the reviews suggest it simply doesn't work.

Has anybody found an approach that does work?

"Has anybody found an approach that does work"

The approach and the material used are two different subjects
I have a 100% success rate repairing damaged HRS elements

It is important to use a high quality High Conductivity Paint that will be expensive

I will be back in a minute when I have found one of my older posts that I can link you to

Better to mask using masking tape. The mask supplied with that kit is about the width of the white lines on the road!
And yes, I have used it successfully on a number of our own cars.
I would be interested in Glassman's opinion on what is the best stuff to use.

Seriously though, don't buy it through Halfords, check you local motor factors, they will probably have one at a much lower cost.

Ignore The Above Two Posts As They Are Not Giving Good Advice

The quality of the High Conductivity Paint is very important, the paint that costs the most is generally the best
This paint is very expensive due to the ingredients used to make it

Do not use Halfords HRS Repair Kits - Do not take advice from people that are not qualified to give it

I hope this helps

Cheers. Doctor Volt

Found It, visit the below link

https://www.tedpella.com/semmisc_html/sempaint.htm

View and read - PELCO® Conductive Liquid Silver Paint

There is a PDF File with details

https://www.tedpella.com/technote_html/16031,%2034...

6 Months shelf life is the problem

You will probably do better by visiting a qualified Motor Vehicle Electrical Engineer (Auto Electrician) that uses this paint on a regular basis

Having used it on several of our own cars over many years successfully as I've said above I'm obviously talking out of my arserolleyes

ETA. I'm still interested in what Glassman uses & where to source it.
And a UK stockist of Pelco - or where you buy it from yourself - would be helpful.

Everyone to their own - Not for one moment did I say you were talking out of your ****(Censored)
There always has been and always will be bad advice, advice, good advice and best advice, it is for the opening poster to decide who is giving the best advice

In my opinion your advice is not the best advice, my opinion is given from my experience in repairing more than several damaged HRS Elements using the best High Conductivity Paint

No offence meant

OK, so shelf life and poor prep are the likely causes of most of those failures.

I know a couple of good motor factors so will look out for the good stuff.

Thanks for the guidance.

OK, sometimes things don't quite come out the way we mean them to.smile

I'd still be interested in a supplier of the Pelco - I did give my usual local factor a call (one branch opens on Sunday) & whilst they stock the Granville they've never heard of Pelco.

Shelf life is a problem because you will only be carrying out one repair and then have to give or throw the remainder of a jar of paint away

I used Pelco as an example, I have now found the correct supplier

Please see RS Components Link in my above post

Silver 3 g Bottle Paint Conductive Adhesive @ £10.04 is a very good price

Not quite sure what you mean there chap, I made a light hearted joke, hence the smiley, getting a replacement window and then told him not to go to Halfords, which is funnily enough, exactly what you said.

There is no such thing as Quality High Conductivity Paint at a much lower cost than Halfords

I hope this helps

The link you posted to RS is £10.04, Halfords is £11.49. Granted not a significant saving, but I'll bet the RS one works and the Halfords one is a bit st...

This link might help to a thread that I posted in a few weeks ago, I can't recommend the Frostfighter stuff enough, worked first time and is nearly invisible. Should only take 7 days for delivery from the States.
