i still keep my stand that prestone sucks. its overrated. since only a select few used it in singapore, and make it sound so great, it seems great. but definitely not the best
there are a lot of threads on lube -.-
permatex works great on type D and type A but sucks on storeboughts.
storeboughts, 3in1 still good enough.
Other lubes tend to "melt" the plastic, including prestone. thats why, prestone sucks.
all lubricants except mr mckenic is corrosive due to the petroleum distillates for the spray to be sprayable apparently prestone has propane, which makes things worst
