It's been awhile since I've purchased any, but I believe was cheaper locally.

The ability to glue acrylic really expands its possibilities. As an example, several years back, I made a vacuum fence for my cabinet saw. It attaches to my Incra TS fence system. With a variable speed control on my vacuum, I can set the vacuum from light to so tight it's hard to feed the stock. It has completely eliminated kickback on my saw and ensure the stock remains tight against the fence. It's also very slick.

I used to use a product like this in 55 gallon drums. put into the needle applicator. on polycarbonate. it dried extremely quickly. https://www.amazon.com/Weld-Acrylic-...DMRDB2FAHRW9P2

This isnít to relevant , but Iíll throw it in here anyways . Itís best not to cut or engrave lexan with a laser.
I knew this but accidentally did it. You canít even comprehend the horrible looking plasma ball of smoke that comes off Lexan, and it damages optics . This is why most companies will not put lexan on their laser engravers .
Itís so strange as plexiglass cuts beautifully with no visible smoke , almost leaves a sweet taste in the air , which I believe the byproduct to be co2 .

For some reason all of our glass shops stock plexi in 1/4Ē thick , but if you want 1/2Ē thick itís always lexan .
No idea why this is . Maybe Iíll ask next time

I donít always insulate , but when I do .
Ok ,I never insulate

Acrylic is shinier and cheaper than polycarbonate.

I've never noticed any difference, but admit that I've never actually looked for any difference in shine.
