+3 ^^ I will be the third guy here to swear by ATP 205. I've used it on 3 vehicles with satisfactory results. As I recollect, the label on ATP 205 wants you to use it by about a 1/3 mixture in a PS setup. Use a turkey baster to suck enough fluid out to make room for the 205, and after installing, give it a few days to work. I think I actually ended up with about 1/2 full of ATP; but it worked. Yes, it is meant for rubber seals, and no, I doubt you have Teflon PS seals unless you drive a Delorean.
