What do you guys reccomend using to put as an undercoat on my mustang. I have a few spots that are getting a little rust, so i wanna patch them up asap. So what do you guys use on your 5.0s?

thanks

 

POR-15 chassis black followed up with some 3M rubberized paintable undercoating!

 

Thank you so much for replying. Do you know where I could get some of that?

 

POR-15 is strictly mail or internet order only as most paint supply houses have thier own propreitary brands. 3M paintable rubberized undercoating is at any good auto supply house like NAPA. POR15.com is the website I think.
