If you say so.
But, I saw no mention, by Sashco, of their Lexel, as a STRUCTURAL glazing adhesive/sealant.


Since you seem to be an adhesive expert, perhaps you can help me.
I needed to attach a velvet Elvis paintin,g to a pink flamingo lawn ornament, so I grabbed a bottle of contact cement. The instructions said to apply to both surfaces, and wait until they’re no longer tacky, before putting them together.

That was 6 months ago, and they’re still tacky.

How much longer do I need to wait?

The story about a famous marine adhesive/sealant that failed was, if I remember the stories, NOT Dow, but rather a 3M product. After trying lots of different stuff on my five opening deck hatches and 8 non-opening lights, I’ve settled on Dow 795. Since I can’t conveniently get the various fancy UV and scratch-resistant plastic sheets, replacement of lenses is a scheduled job. The 795 has never leaked and outlasts the lenses.

Plastic demand has been an all time high.
Royal plastics in Toronto has been busy.
Believe it or not a Home Depot catalogues their scratch resistant E style acrylic. It’s special order here at least. Royal plastics have other local commercial outlets. One shop CnC cuts exact pieces for folks. I built a vapour heat box with their sheets and it was very pricy. I image lens thickness would be considerable more. Maybe over $400.00 for a 4x4 sheet. The sheet I used 10m was $120.00
