Most of us are old enough to know people or be people who were affected by "the good stuff". I have no idea what I have a sensitivity to, but contact with certain chemicals can cause a reaction as pleasant as a light case of poison Ivy, or a genuine "it sucks to be you" case of blistering, peeling, and when nothing is left to blister and peel you get the cracking and bleeding thing. That is generally accompanied by the "mummy prayer" thing where your hands are bandadged and you pray the blood stops soaking through and it'll be over soon. Soon being a couple of weeks. So by all means use Napthas (no real need for a liver) Methyl Ethyl Ketones (MEK) Heck people would open the hatches on my aircraft elevator pump rooms with signs saying "danger" neurotoxin, carcinagen, yada yada, because they heard that cellulube strips paint (it does).
I implore my friends to take care and use some common sense and a little more labor to live a lot longer and more comfortably. Relax and let safe and light duty chemicals do the work with time.
Tis why I say I use Makers Mark bourbon. No hurry and the wait is not so bad. Even if you only spray 409 on the machine.
