Does anyone have any experience using the new hot melt polyurethane adhesives such as the HiPURformer system by Titebond/Steinel?  I’m considering it for use on custom jobsite trimwork, primarily interior.  How well does it hold joints?  How easy is it to work with?  I insist on tight joints.  Does the high viscosity of the glue make it difficult draw the pieces together?  Any feedback and tips on using it would be appreciated.
