Rust-oleum rust dissolver !! Works

Gotta wear a mask with those chemicals.

Crap stuff

I love that stuff!!!!! Tried it about 3 years ago on my mini van and found out the rust was worse than i thought sprayed it on the sliding door 2 or 3 times in a half day it disolved every bit of rust and turned out the rust was all the way through the bottom of the door and have used it several times since i did get 1 bottle that wasnt very strong about 2 years ago but so far its the best gel i have found!!!!!! But i havnt tried evaporust gel yet dint even no about it until today never seen it in the stores before!!!!!!
