I bought a bigger bottle after reading glowing reviews here. It gives a nice finish but man, seams it gets into where two pieces of plastic touch, it creates the most annoying creaking noise. Two materials coated with this stuff can not touch. The dash in my Crown Vic, especially the passenger airbag and what surrounds it makes a ridiculous amount of noise after treating with 303. I sprayed it onto the dash liberally since it is an older car that has sat outside.
