Magic I bet he was a character too!
I just have framed pictures of an Activa and an XM on my living room wall Along, naturally, with portraits of my girls...
You never know James, it may well be the perfect stuff although the old stuff bears no relation to aged mastic... Think of very dry thickly applied black emulsion paint!
Black Bostick was, according to the gurus up on the vintage radio forum, the stuff originally used but sadly it's no longer available
That's the stuff most of the gurus on the VR forum recommend Chris... Some even suggest instant gasket - just as long as it is not the sort that liberates acetic acid as it cures...
Given the nature of the materials to be bonded, that would seem the perfect stuff Mick. I take it that's the kind of adhesive used to bond rear-view mirrors to windscreens. Surprisingly, caution was expressed on the VR forum that such adhesives are considered too permanent and would make glass replacement very difficult should it get broken in the future... I'd suggest that risk is so minor as to be inconsequential as in 45 years of using AVOs I have yet to break a glass... And I've used AVOs in some pretty challenging situations too...
Thanks Chris, excellent I shall get some on order I reckon that will do the job a treat...white exec wrote: ↑02 Feb 2021, 11:39It's silicone sealant that contains acetic acid, Jim.
Polyurethane adhesive/sealant cures by absorbing atmospheric moisture. A thin film of it will 'turn to rubber' quite quickly, but a thick mass of it (eg used to refurb a silentbloc-type mount/bush) might take days or even a couple of weeks to fully cure.
You should have seen the results of me using Gorilla glue on my specs
