My car started leaking gasoline a week ago. I haven't drove it since the leak started. The leak is on the under side of my car ('95 honda accord, if that matters). I've heard about some stuff that can be used to patch the leak up. I can't remember what it's called. I went to autozone to get some, but the guy there said that since the leak was on the underside of my car, this stuff wouldn't work. He mentioned that it's because the area needs to be dry for this stuff to work.
Well, I've heard from other sources that this isn't true. Even if it is true, all the gasoline has leaked out of my car and the spot is dry now.
My question is, will this stuff work as a temporary fix to my problem? I don't want to walk all the way to autozone without knowing the answer to this question first. I plan on taking my car to the shop and getting a more permanent fix since I assume this stuff wont last for too long. I wont have much money for a few more weeks though. How much would a permanent fix cost me?
