High viscosity, non-corrosive. There are other brands that are similar and cheaper, we have always used this brand. Whatever brand you choose is probably good, but be aware you are trying to find a GAS LEAK. Just don't use dish soap and water, they are caustic and can rust/seize connections/fittings. Leave soap and water to check for air leaks in the tires.
