I'm looking for a glue that is good for creating an invisible joint in acrylics, preferably even if you glue two pieces "face to face". I don't want the fogging that some glues give.

Preferably, I want it fairly liqid, so it's easy to apply, and I don't mind at all if it's slow.

If possibly, name the type, not just brand, as I'm in Sweden, and most US brands aren't available here.

Anders, what is used for making acrylic fish tanks is this stuff-

It is water thin and similar to what Russ uses for acrylic [he uses a chemical of some kind]. I is drawn into a tight fitting joint and produces a clear bond. It actually solvent melts the plastic together. Both #3 and #4 [longer setting time] are used. The #16 is thicker and easier to use if the joint is not perfect and/or the appearance is not important. Good luck, hoping the amazon listing will lead you to something similar in Europe. Gene

Thanks, I'll try to find a Swedish supplier (while I can order from Amazon, a $10 order will add on $20-30 in freight, import tax and so on, and deliver will be 1-2 months, and that is if they'll deliver overseas at all...).

Look for SciGrip adhesive for acrylics, sold or made by Weld-On. The Type 16 is medium bodied (about like corn oil) and works well for joints with gaps; Type 4 is thin (like water) and works better for tight joints where you'd rather not see a fillet of adhesive after the parts are glued. A plastic squeeze bottle with a thin needle in the lid works well for applying the Type 4. I'll often use a disposable 10 mL syringe for the Type 16.
