Have any of you chaps seen this on your T8s?
The can has been totally degreased and allowed to dry for a day or two. It would appear as though the weld points are possibly acting as 'sweat pores', releasing excess oil once the surface layer has been cleaned off.
These same points also seem to extrude a fluid when a neoprene cover is used. After only a few shots a small area of fluid can be seen which smells strongly of ammonia.
I would be grateful if anybody can throw some light on what might be going on here.
