It is better to get in touch with these components directly. Use safety measures like- hand gloves, goggles before applying it on your car or car’s engine. You need to be also careful that there is no source of fire or electricity while you are pouring it in your car because these are extremely flammable and eye irritant. Also, keep these products away and safe from children.
