Hey there, OK so I order these whiteface guages

When I got them the instructions said to aquire some application fluid from your local sign shop that did vinyl applications. So I went to my local shop and showed the guy what I got and everything and he told me "Basically you are puting water on your dash and if any of that what gets into the wiring your screwed." He said to dry stick it on there which would work but if I screw up and have bubbles in there Im screwed but with the application fluid it gives you time to fix the bubbles while it slowly dries. Now my question is has anyone done these before? Did you use the fluid and have you had any problems? If not how did you do it? Also I have the digital speedo so thats another reason why I am doubtful bout using that fluid. Thanks for the help.
