This glue is great. It works just like the best CA's out there. I have been assembling models for 34 years now, and this glue is excellent quality. I highly recommend it.
Parts must be in contact already, this glue wicks into your parts well.
If you are doing balsa end to end, cure time is about 2 seconds.
If you are laminating or linear grain gluing, the cure time is 5-6 seconds.
CA hinges cure in about 5-6 seconds and the control surfaces are very well adhered.
I roughened aluminum with 320 grid and glued two pieces of aluminum. The glue joint was extremely strong.
I roughened plastic with 320 grid and glued it together with this glue, and the joint is also extremely strong.
I secure carbon fiber to airframes with this glue, and it works well there too. You must glue the rougher surface for carbon fiber.
I highly recommend this product.
