i saw on melevsreef that he uses weld-on products to glue the acrylic together. I have looked all over my area for it and no one carries it and cannot tell me where it is sold. Anyone been able to find it other than online? I only need a very small amount and refuse to pay almost $30 for hazmat shipping charges. Does anyone know if i could use Locktite glue made for acrylics? Lowes carries it with all their other glues. I am making a 40g breeder into a sump and i would only need to glue 2 joints with this stuff. thanks.
