I know I have talked about this here before, but on another forum, I know shame in me, A new post has been started on using Ospho on cars, trucks. There are some links where deadbodyman shot several videos on him doing this. There can be some heated discussion on somethings, but not too bad. You may know if you read some of my posts on rust, that I am a believer in doing this..
The older I get the more I like to use-see video. It answers most questions before they are asked.
I will post a like the his post and you can go from there. You do not need to be a member to read.
