So the needle doesn't clog with acrylic?
No! The Weld-On isn't Acrylic. It "Welds", or melts it together. Its more than just an adhesive, its a chemical reaction with the Acrylic itself. And the stuff is tough.
Which weld-on did you get? The stuff I used, 13 I think, was thinner than water.
Justin showed me how to do it, stop by and ask him about it.
