was finishing up my windows on my top hat and was using aquaseal to glue the plastic in. i got some seal on the window and used some denature alcohol. everything was set glued and clamped. within a minute o wiping on the alcohol i heard a pop and the watched spider web cracks form where i put the alcohol. who new. i was using optix acrylic sheets i got from the big box. i wont be doing that again. now regarding aquaseal it glues the acrylic really well and aheres to almost everything. the down side is that there i not much that can thin it out. there is one thinner that they do use with but i cannot remember the name. i think ist is toluene is sold with the aquaseal. the other downside is once it has hardened there is nothing that will disolve it
