Acrilic and Plexiglas are the same.
Plexiglas is the trade name given by the inventor Roehm & Haas .

I’m just about to do one on Kristy, Bill. It had cracked last year and I had it done professionally by a company in Ft Lauderdale. They used a clear silicone caulk which leaked a couple months later.
From what I’ve been reading, a glazing sealant by Dow (DC795) is what many professionals use, and what I’m going to use. My hatch lenses are plexiglass, not acrylic. I don’t know if DC795 works on acrylic or not.
For what it’s worth, there’s another product called DeBond that was designed to release 3M’s 5200 sealant. I used it to get the hatch frame off of the deck and it made that job, and cleaning the old sealant off of the frame MUCH easier.
There is a specific silicone for bonding acrylic to aluminum. I forgot which one it was. Last time I called GE silicone division and they gave me the number it is not your regular silicone. Also when I rebuilt my last boat I spoke to the people at Atkins Hoyle. They recommend to prime the edge of the Plexiglas and the frame with toluene . It made the surfaces very sticky and the hatches never leaked. I also used under the genoa cars and the silicone stuck like crazy to it.. Be careful as it is very toxic.
