How long should the wax sit on the car before wiping off? What is best was to use on a silver turbo? I used the porsche wax and it said to let the wax dry completley. Not sure how long to let wax sit on car. What wax will last the longest? Thanks. Dan

 

once you can wipe your finger over it and it all comes on. For most waxes that's no more then 30 minutes.


I've been using a lot of Meguiars new NXT lately, I think it looks great on silver. Something else to consider would be P21S or S100 which are the same product but S100 can be found for $10 cheaper at your local Harley dealer.

A lot of members here also like Rejex.

 

and as far as waxing the longest, that really depends on your environment and how you treat your car. Most wax's i've experienced tend to last about 8 weeks. I usually re-wax every 4-6 though cause i'm a detailing nut
