I see your point, but don't think there is much dussuading going on. More like helping people think the process through to accomplish their goal. Learning new skills is great and should be encouraged. But when it stops being great is when someone (not implying that the OP is that "someone" of course) gets the notion that they can do an incomplete job and have the same results as if the complete job had been done. My feeling is that if someone wants a reliable shutter than they should learn to do the whole job or send it to someone who does. Whole job = clean and lube per manufacturer spec. If someone can tolerate a potentially unreliable shutter, then flush it with solvent on it and see if it works good enough for the need.
