A Touch of Glass

As I’m planning to get rid of most of Herman2’s vast window acreage, just keeping the wee port-hole ones and the slidey open top sections of the back ones, I’ve been musing on the best way of covering over the offending glass. I dinnae really fancy welding [or more likely getting someone less cac-handed than me to weld] metal plate over them, as I’d have to strip the inner walls of the van beforehand, to stop them going on fire. And, seeing as it’s a professional Devon conversion [albeit to a minibus], I don’t really want to have to start ripping all that made-to-measure interior out, if I can help it.

Amongst several musings on the subject, I wondered whether it would be possible to build up layers of fibreglass resin and matting, over the glass [for strength] and then paint on top of that. Asking round and searching for the answer to the crucial question as to whether or not fibreglass resin/matting would actually stick to glass in the first place, did not throw up any definitive answers, so I decided to conduct an experiment.

I thoroughly cleaned the corner of a glass panel out on my balcony and then put a layer of fibreglass resin and matting over it and left it for a week, to good’n’properly cure:

At first, I thought we had a success on our hands. Scraping at the resin around the edges, it seemed pretty solidly bonded onto the glass and the matting looked pretty well embedded in the resin. But then I wiggled the knife blade in under the corner of the matting and this happened:

Whoops!
Whoops!

So, the short answer to the burning question “Does fibreglass resin and matting stick to glass?” is “No. It fucking doesn’t!” Back to the old drawing board!
