Rust pitting repair

[third base]

O.K., i know a lot of pople think that POR is the greatest thing ever invented to stop rust but that is simply not true. after applying POR it dries very hard and can eventually peel if done on edges. in order to use any kind of their putty(any kind!) the POR has to be tacky when putty is applied. then if you want to primer over it you have to break the surface quite a bit. don't bother using a tie coat primer for it is practically the same as a good epoxy primer just apply after POR has dried and use a few dust coats before you cover surface completly. I have had many discussions with the dealers in Sac, cali.. about their products. sadly i have found out the hard way and have personally used A LOT of POR. I don't even want to go into that. so if you have something to patch. cut it out, patch it, clean it, primer and topcoat. if done correctly you shouldn't have any problem with rust.
P.S. if you do use POR make sure to wear the proper mask. water is it's catalyst and it can dry in your lungs. it happened to me and I got very sick and all that happened was I could slightly smell it though my mask. Good luck!
