i drive about 90 miles every day (monday through thursday anyway) going to and from college..(45 miles each way).. and the salt is applied HEAVY at times... i wash it and by the time i get to school, about 45 miles away, most at about 65 mph, my car looks like a salt lick... i washed every 2 days because i couldnt stand seeing the salt on there lol.. and yes, im using a good soap... pinnacle shampoo, or megs deep crystal wash..
Aha! Might've spotted the culprit(s)
I can sorta understand the frequency of your washing, given your situation. I did that sort of thing when I used a Porsche as a year-round commuter car...seemed like I washed it every time I drove to the U.
To be honest though...these days I let 'em get pretty nasty before I wash 'em
But I bet you're not gonna do that, huh? Since you'er gonna keep washing all the time

I'd suggest:
Change the shampoo(s). That Deep Crystal stuff is seriously lacking in lubricity and encapsulation, *NOT* money well-spend IMO even at its low cost. Using it in strong concentrations could very well impact your LSP's durability too.
The Pinnacle Bodywork Shampoo is funny stuff...yeah it has great lubricity and encapsulation, and it cleans really well. But, much to my surprise, it was always very harsh on my LSP, and I do mean *VERY*, so much so that I quit using it for that reason (still have at least a gallon sitting here). Note that it used to be the *only* shampoo I'd use, I liked it that well...just couldn't deal with rewaxing all the time.
I'd switch to Griot's Car Wash (my fave but pricey), or DuraGloss or Optimum (their regular shampoo, not the ONR stuff). People whose opinions I respect say the latter two are about as good as the Griot's and they're sure a lot cheaper. I used to use Meguiar's #62 (after the Pinnacle and before trying Griot's) and it's not bad either (not too pricey in gallons from the local autobody/paint supply store).
