Red Angel Stop Leak - Need Advice

also, if you're going to use a black light,get some CSI yellow tinted glasses as it will help in locating UV dye. i work for RobinAir. in the description of "oil based stopleak" it stays in the pag oil and has "velocity activation." at the end of deep recovery, the RRR machine will perform a "oil drain" cycle. it would pressurize the container that holds the oil/stopleak and opens a solenoid where it flows through a tube into a bottle. i could see it clogging the solenoid and tube. but they always get clogged. it's probably in my top 10 most frequent repairs...
