Good sealant does the job
Perfect for replacing sealant on Perspex boat windows. However watch the sell by dates - sometimes these are supplied already beyond the use by date

Best quality of silicone I've used
This is genuinely really good stuff. I used it to seal copper to painted wood and it worked perfectly. lovely smooth edges, no strong odours (compared to some other ones I've used) and as it's neautral it doesn't react with the bare metal so perfect for this application. really happy I found this one, and got plenty left for another job.

Out of date
The silicone sent was out of date. Not terrible. But expensive for it to be out of date.
