I found another "Rust Neutralizer" called "Rust Mortar" from SEM. It netralizes rust and leaves a Zinc Oxide type finish. Similar to Metal Ready from POR15. It has the same active ingedients as Metal Ready. It is relatively inexpensive and can be purchased from you local SEM dealer. However, I am not sure how good it is since I have not heard of anyone else using the product.

I am planning to liberally spray it into unreachable areas such as the door sill, inside the lower fender wells, inside bottom of the doors, and the cowl area. It seems to do a good job neutralizing surface rust and is supposed to prevent rust.

Anyone have any experience with this product?

I have used it with great results. Putting on every piece of metal as I repaired the rust in my car. and the complete top as I too stripped the paint due to a disbonding check problem. I only use metal ready where I am going over it with POR 15.
