a few weeks ago i was dead tired and didnt hae time to wash my mom car. she told me to just take it to the local car wash. normally id say "over my dead body". but she doesnt care anymore than anyone else. so i took it. upon arriving i see like 12 guys working. each doing a different job. i asked whgat his services were. i tried explaiong him what a clay abr was to see if he used one. he had no clue. then after everything he said that a layer a teflon would be applied. i feel bad for the fools who buy into it. i have tried duponts teflon tire shine. attracts less dust than silicone dressings, but no better than any other water based dressing. it does give a very good sheen to tires. i like it.
