It is known that tin-whiskers grow from compressive stress such as may be introduced during tin plating from the traditional tin plating baths.

My question is, can tin whiskers form from pure tin plating that is deposited by a brush tin plating process (AMS 2451, AMS 2451/12)?  Is there any available test data or other data that supports this (I have plenty of info on growing tin-whiskers on other than brush plating)?  

If tin whiskers can grow on brush tin plating, will the tin whisker mitigation methods in IPC/JEDEC JP002 mitigate the potential for growing
