Thanks Jesse and Reef Bass, The ones I saw until you mentioned the others (still working without glasses) were the sloped area on the grease gun, between it and the WD40 can and the area under the trigger of the grease gun..
The pushlock fitting is about 2" in front of the WD40 can, suprised the WD40 can didnt have more light reflections in it with the way the overhead fixtures were swinging..
Gonna try some with my pitcher plants this weekend if it doesnt rain...
