We've given the following new car products a good going over
3M Silicone Lubricant
Silicone lubricant does everything ordinary lubricants do - except that they're not oily and don't drip everywhere. Some marques recommend silicone lubricant to treat rubber seals and convertible tops. This 3M Silicone Lubricant ($36, 241g) immediately stopped door squeaks and made rubber supple.
Armor All Extreme Tire Shine
This new tyre foam from Armor All ($56, 425g) has what's called a precision applicator, which squirts a fine arc of the misty, nice-smelling substance that distributes evenly on the tyre. The trigger-like nozzle is ergonomic, and in a short time tyres are blackened beautifully. The shine isn't as extreme as some might like, but I like the effect.
Turtle Wax F21 Tire Foam & Shine
This shine is no different from most tyre foams: spray it on, leave it to sit for a while and the tyres become nice and shiny. The F21 Tire Foam & Shine ($38, 595g) smells quite pleasant and a nano agent blocks the UV rays that quicken the tyre's ageing process.
