Can I use two cans of Super Seal on my vehicle?

One can of Super Seal is all you need to seal pin hole sized leaks in your system. In order to determine the size of your leak use the following rule of thumb: your car must be able to hold a refrigerant charge for at least two weeks. If you car can hold a charge for two weeks before blowing warm again, then Super Seal will be able to patch your leak. If you have a large hole or leak using two cans of Super Seal will not help.
