Some people squeegee and some don't. Fine. But if one is trying to teach a beginner how to get good results with the least number of potential complications/problems, I have to question the recommendation to squeegee or wipe the wet film in any way. Proper use of a wetting agent substantially reduces drying spots. Using distilled water with a wetting agent eliminates drying spots. If either of those methods are used, a squeegee adds no value and only introduces more risk. One should generally not assume incremental risk when there is no potential reward.
