I used Redi-Strip and they did a really nice job. There are a lot of stories around about the chemical staying in hard to get at places and I think that the stories flawed. As I found out with my doors, there are areas where the metal is pinched over another piece, such as the door edges. No blasting or chemicals can get in there. When you open up the seam to replace the skin, there will be rust in there. People experience rust along there sometime after the whole job is finished and blame it on the chemical stripper. In reality there is no process that will remove that rust.
