I use that mix as a converter for pits and any junk I can not get. Yes krud kutter the must for rust at walmart. Works great for heavy applications as well. Simply more of the krud cutter and make a strong mix of kk, water, vinegar and dip item in it while you sleep. I use a wire wheel on my drill or a wire brush before the treatment for few min to remove heavy flaking. KK has phosphoric acid in it which does convert rust and remove it as well. It is not a supper strong mix, tends to be a more user friendly rust remover. so I use it with vinegar and water to make the job easy. I shoot the parts with some rustoleum rust reformer to help finish any pits I may have missed. Kk will etch the metal if you leave it submersed in a mix with only water for to long.
