SLK R172 Rear view mirror

[TommyM]

<div class="bbWrapper">The interior rear view mirror fixing has detached itself from the windscreen. I have tried to glue it back on with Tetrion Mirror Fix Bond glue but this was unsuccessful. It would appear that it was originally fixed with a thin double sided clear tape. Has anyone had any success with bonding the mirror back on.<br /> Thanks. Tommy</div>

<div class="bbWrapper">If it's like the R171, the only long-term solution is a new windscreen. Don't ask me how I know...<br /> <br /> See this thread : <a href="https://forums.mbclub.co.uk/threads/r171-interior-mirror-loose.266111/" class="link link--internal">R171 Interior Mirror Loose | Interior</a><br /> <br /> The Sikafast only lasted a year or so. I've no idea what the black stickum I referred to was, or I'd have bought some of that; it lasted longer than the Sikafast. There may be something available that actually does the job, but I spent quite a lot of time on the internet and never found it.</div>

<div class="bbWrapper">I would have thought that 3M may have something in their range to cope with that job.</div>

<div class="bbWrapper">If you want mirrors to stay on you need one of the UV activated mirror glues....usually a <i>UV</i>-curing cyanoacrylate <i>adhesive</i>. Like the factory use. Nothing else lasts in my experience. Just use it on a sunny day otherwise it wont cure!</div>

They may also suggest an alternative adhesive for the application.</div>

You'd need to be a dasb hand with a scalpel, though, because the actual contact area between mounting plate and screen is quite small. or at least, it is on the R171.<br /> <br /> Good luck, and please let us know how you get on.</div>

<div class="bbWrapper">The mating surfaces would need to be very clean before mounting the mirror. I use a product called Metamark surface cleaner for jobs like this., it is used for cleaning when fitting large format graphics to shop windows Etc. I cleaned my windscreen with a good glass cleaner, then did it again with Metamark and was amazed by how much crap was on the cloth.</div>
