Hey - i am coming up on a year with the 4runner and have enjoyed it so far. i have taken it wheeling almost every weekend. i had to look at about 4 trucks before finding one in decent shape rust-wise in the Northeast and i finally did. After one winter with it...i decided im going to POR15 this thing, as i do want it to last for many more years and figured id better get this out of the way. going to buy a quart at a time and do sections at a time over this summer. i still need to figure out if im going to replace the stock skids or treat the ones i have (one small hole in front skid.) i decided to do this after i just recently degreased the entire underside with a strong simple green solution - this project will be worth it where i live, and with the amount of money i have into this thing already with a few other decent mods id like to do as well.
