Ahh prist. Brings back fond memories as a 1Lt adding prist as we serviced our C-21 ourselves at austere Eastern European locations. I've seen guys get that stuff all over their clothes/hands/etc, but I'd be willing to bet that it was less corrosive and hazardous to one's health than some of the local liquor (and female companionship for that matter). We took it with us everywhere we went, and added it ourselves via an aerosol can with a tube that hooked up to the fuel nozzle, every time we filled up. I once questioned how smart the practice of self-servicing (no pun intended) was when I was standing on the ramp one day while a buddy was fueling the jet. I heard some commotion, and looked over just in time to see a huge spray of fuel erupting from the filler port as my counterpart had forgotten that aviation nozzles do not feature the same auto-cutoff feature that you'd find at your local gas station. Needless to say, the poor guy had a bad day, as his flightsuit was soaked in jet fuel, and he was forced to buy beers for the rest of the evening. Good memories.

that and if you get it on your, dont touch your face until you wash it off

Any thoughts? or comments.

Well OK, if you're not bypassing the oil filter before you fly, are you going to add the Prist to an aircraft with a functional fuel heat system?Fair question?

An oil filter bypass lite is a "Land as soon as practical" situation. There is an unknown reason it is bypassing. Metal and ice are two possibilities. I can't remember if the checklist says anything about preparing for a possible engine failure, I'll have to look. I think it would be on my mind!
Now, back to the prist issue. I don't think I would be adding it just in case the oil filter bypass lite comes on. You would be looking to prevent multiple failures in my opinion.
