So Ive been looking into touching up some chips on my hood.. got quite a few small ones. So lackstift comes right from Audi, thats a plus, however, the touchup123 system looks to be effective and easy. Which way to go? Anyone have experiences using either product? Do you rub the touchup123 over the entire hood (or whatever other panel you're touching up)? Let's get this question out of the way once and for all, thanks.
