Have any one use this product before . Recently , my car develop a small leak around rear main seal area , then I use this product , and eventually , it stop the leak .Maybe it good for temporary fix ?
I wouldn't use it in a car I intended on keeping for longer than a week or 2... IMO fix it properly and don't risk stuff like that.
Id fix it when you do a clutch change as long as its not pissing out and leaving a pool on the garage floor if just a couple of drips it may stay that way for ages just keep an eye on oil level.
