I don't know if anyone would have complained - its possible no one has had their machine cleaned after using this method - that was my original question. There is another thread on this board with comments from a service tech, noting that there is residue inside of machines that he cleans after someone uses the spray basting method. So, if that can be found in the machine, I'm wondering if the glue will also find a way to get inside. (that is assuming people use the spray after it is dried, which I am sure they do) Thanks for all the replies!
