Extrernally mounting a gauge on hood
What is the besy way to mount a gauge on the hood? Are they sealed for weather, what to look out for?
I was looking at sandwiching the C mount with 2 soft rubber cards on the rear of the hood vents by the windshield. A couple of screw and nut through the vent slot to secure it as a base. Then use a normal gauge cup with a installed mechanical gauge , like vacuum, boost, etc.
How have others done this. Looking for ideas.
What rattle can paint for cups cause rustoleum fusion flaked off?
