My GT '03 Steel Blue gets very dirty/soiled, i doesn't last even 2 days after washing when its (very) dirty again... i wash it with Armor-All (Car Shampoo), a spounge and a flannel.
I dunno what to do or what's the trick to keep it "clean" for long than 2 days, i use normal streets/paved always it's like i was always driving over dirty roads and the dirty is too sticky.
I pour water all over the PT and if i don't start to wash it immediately (and i mean immediately) it remains same dirty/soiled
and sometimes even worst, so i need to wash it fast (i mean really fast)if i want it to look at least decently.
I like to turn heads to my PT but not for its dirty/soiled look [

Any help would be appreciated and many thanks in advance
