Toyota Repair: 1995 toyota camry LE, toyota camry, seal oil

Question
my camry has a rear main seal oil leak, and someone told me about this Bar's rear main seal oil repair and i just wanted to know if it was any good, and if it would mess my car up more. Because alot of ppl told me to use it and then other ppl told me not to because it was a temp fix and would screw things up more?????

Answer
They're right it is a temporary fix and maybe not a fix at all, the reality is that once a seal is worn and leaking it has to be replaced, the additives don't work so don't waste any money on them, they are a band aid at best. The solution is to replace the rear main seal or trade the car in on another one.
