Yea klean strip etch stuff works good too it is right next to krud cutter must for rust at walmart great to add a bit for heavy rust removal after a couple tries you will find the sweet spot. it is a little bit more potent great for heavy rust, it will etch the metal if left in to long it does help with adhesion. The batch I was using was mostly for converting and pits, I sprayed on waited for them to turn black. But yes that stuff works great with vinegar and water, just do not add to much... You can always add more but cant go back.
