Yes, coolant on the spark plug tips will kill them in short order.
You can do a quick & dirty test with a DMM...
Measure resistance from the spark plug wire end to the center electrode (in combustion chamber).
Check this same measurement on one of the brand new spark plugs.
The used spark plug should be *less* in resistance due to the center electrode wear down slightly.
If the spark plug is "fouled", the resistance is going to be significantly higher.
I forget what what these NGK BUR/EQ's spec around, but the number 1.1k-ohm sticks in my head?
Don't quote me on that...
