From Jimmie Meeks of McDaniels on August 21, 2014:
While I appreciate the answers from each person, what part of immersion service was not understood. Holidays or pinholes are not acceptable on any coating job, immersed or not, that I am aware of.

From Robert Ferguson of Greenmane -Pedersen,INC on August 20, 2014:
Zero

From Shane Gannon of Northern Metal Fab on August 15, 2014:
Zero holidays are allowed for immersion linings. Sponge wiping the coated surfaces with a low voltage holiday tester works great for detecting holidays when the lining is 20 mils or less. High voltage testing can be used on linings thicker than 20 mils.

From Daniel Liu of APC on August 13, 2014:
No holiday can be permitted for immersion areas.

From Navin Kothari of Kotech (QLD) Pty Ltd on August 12, 2014:
Having no holidays means completely free from pinholes of any dimensions.

From Simon Hope of Bilfinger Salamis on August 12, 2014:
Immersion systems are designed to be pinhole- and holiday-free, hence, the need to undertake suitable holiday detection. Any such defect negates the whole purpose of the lining and the classic 'if you can't see it, it doesn't really matter' attitude is what leads to premature failure of so many systems. Proper quality control, rigorously upheld, can save a fortune in the long run.

From Navin Kothari of Kotech (QLD) Pty Ltd on August 11, 2014:
No holidays are permitted.

From Steve Brunner of WPC Technologies on August 5, 2014:
Linings for immersion service should be pinhole-free, meaning zero pinholes. This is a relative easy task when applicators follow coating manufacturers' instructions.

From Billy Russell of D&R COATING INSPECTION on August 2, 2014:
Zero holidays should be permitted for linings in immersion service.

From Per Gabrielsson of Free Lance Consultations and Inspections on July 31, 2014:
Not only holidays are detrimental.  Also, overthicknesses are to be avoided, as they will lead to solvent traps and intercoat crackings. Always specify minimum and maximum. dft's And do not always believe in what some of the paint manufacturers accept, that 2 x minimum on critical areas and 3 x minimum on non-critical areas would be safe.

From Freeborn Enuvwaria of A coating inspector on July 30, 2014:
Not even one holiday should be permitted, because it will cause a severe coating failure in the near future.
