How does the concave or convex curvature of a surface affect the WFT reading?

From PARVEZ SHAIKH of SANDVIK ASIA PVT. LTD. on September 4, 2013:
There should be no problem for measuring the wft on concave or convex  surfaces if you use use an appropriate tool for measuring the surface. In  both these cases, you cannot use a comb gage, but you can use a circular gage that can be rotated on the surface.

From Tom Swan of M-TEST on July 31, 2013:
As long as the wet film thickness gauge is used perpendicular to the curvature, concave or convex, there should be no error unless the surface is curved in 3 dimensions, i.e., it will work on a pipe if used on its length but not on a sphere. You could use a wet film wheel on just about any curved shape since there is only one point of contact at a time, the exception being on very small concave surfaces where it would not be practical to use it.

From SUDALAI RAJ of Akzo Nobel Coatings I Pvt Ltd on July 27, 2013:
The WFT gauge with convex or concave surface will show inaccurate readings on both convex and concave surfaces because  it is designed for plane surfaces. With a concave surface, it will show less than the actual film thickness. With a convex surface, it will show more than the actual film thickness.

From Atul Patel of ASP Engineers & Contractors on July 6, 2013:
A wet film thickness gauge is designed to be used on a planar surface; hence, if the intended surface is not planar, the reference markings on the wet film thickness gauge will show false readings.
