Recently bottomed out a bit and scraped up a few areas underneath the car. I'm thinking that it might be a good idea to put some rust coating on the surfaces I may have scraped, since I'm guessing any coating that was previously on there is now gone. Anyone else done this and have a particular product they have used? Thanks

 

Definitely a good idea.

 

Rust Coating JUST doesnt take well unless the car is comeing out of the showroom---Something that works great is Galvanized Paint---It has Galvanized powder in it and is used in the pipe industry when 2 galvanized pipes are welded together or welding/gringing on anything Galv.---Good Galv Spray is 10-15 $ a can ---Spray. I use it on anything thats prone to rust

 

I forgot what brand but there are some good stuff at the local autoparts.
