The buff hammer has always been a confusing issue, especially for new players. If something is broken, you hit it with something. This leads to quite a few people accidentally whacking things with the buff hammer when they are broken. Even vets do this by mistake on occasion.
My suggestion is to remove the buff from the 'whack it' category and add to the 'spray application' catagory.
Change from
DynaBuff Industries Kit to
DynaBuff Miracle Oil. Basically, WD-40 or whatever your favorite brand may be. It is universally known to make things operate faster and more smoothly. Simple to understand, unmistakable, and innuendo friendly to boot.
*Power-lube is an actual brand of motor oil. I found this image when looking for old oil cans.
