Selected Answers

From Craig Gordon of Helmut Fischer AG on January 24, 2017:
You should use a gauge and probe that has curvature compensation  or a probe with a small tip to reduce the effect.

From Anthony Betz of N/A on January 23, 2017:
If you calibrate the your gauge on the blasted surface prior to coating, your readings should be accurate.

From Paiboonsak Saengsomboon of JT Marketing Co., Ltd. on January 17, 2017:
It depends on the radius of the curve..
