I live around dirt roads and want to know what wax you guys recommend for those conditions. I know dupont has there own thats supposed to resist dirt and such.thanks

 

I like the collonite 845 insulator wax for daily drivers like that a good coat will bead a year even with drive thru car washes

 

I use the Dupont teflon wax. It works very well, however, i have not used other brands so i cannot compare. I have gone up to 6 months and still noticed beading. Plus it gives the surface that nice, velvety touch

 

honestly, you may want to look into a sealent such as zaino or tropicare...id go zaino though

 

You proabably want to use a synthetic sealent....they don't bring out a super deep shine like a carnauba wax (from whatI have heard)will but they last for a whole lot longer and it seems like that is what you are looking for...

i still swear by turtle wax... ive tried that spray on crap and it was a waste of time and money...

 

I can't recommend a good dirt resistent wax...
However, I hope you plan on using a clay bar before waxing if you have a lot of dirt roads. Washing it gets most of the dirt out, but there are tons of particles you just can't wash out.
Second, using a microfiber towel and car detailer spray should help improve the durability and life of the wax after put on your truck. Just use it each time you wash it, it will seem as though you just rewaxed it.
