where are you guys learning this from? using ipa for spot treatment is absurd. ipa wipe downs are used normally for prepping surfaces PRIOR to an lsp so why would you use it on TOP of one? makes zero sense.
take the advice of items like ONR/waterless/detailers. if you question these products in terms of scratching your paint or are nervous with the amount of contamination on your paint then you've answered your own question...aka wash your car.
