There is a bit of rust on my car. Just curious if any of you have heard of POR-15. I'm pretty sure it helps to prevent rust but does it actually get rid of it? I'm always afraid these products don't really work.

ive always heard very great things about that stuff! but dont expect it to be a miracle paint.... if the spot is to badly rusted and thin.... its not gonna help and structure...... and your gonna have to cut and weld in new steel patches......

but like any vehicle... the problem isnt always on the outside metal that you see... most the time it rusts from the backside out and then thru the paint....... cause of water and dirt/grim behind the panel. thiers realy no easy way thier!

 

It will stop the rust from getting worse, assuming it is only surface rust. Sand down the rust, apply product, done.
