I used to play around with acrylics back in the 80's so my memory might be off but for solvent I used methylene chloride which is also known as dichloro methane. At that time I worked at a lab so I always had it handy. For uneven joints I used to take the cuttings from my jigsaw (the powdered acrylic) and disolve it in a small bottle of solvent, the more you add the thicker the solution. It also dries completely clear, no need to purchase glues of varying consistency, just make your own
