Your final seam will never be better than your beginning edge. We use a joiner to prep the edge for general assembly but a hand scraped finish used on our art quality work yields the best results. The other glue is 2 part. It is much harder to use, messier and in my opinion does not give as long a lasting or strong seam on average. It is used most often in furniture manufacturing where seams are made using very thick material.
Solvent adhesives are harder to use on thick acrylic.
Acrylic often forms some gas as the solvent reacts. Cyro has a web site. They have fabrication manuals available and will send them to you or tell you where you can get them. If in Arizona, Daytona plastics in Phoenix has them. All pictures on our site are links to more information or a larger image.
