Removing Rusts from BMW Cars

[mgblks]

Could anyone share how to remove rusts from 18 years old BMW cars?

Rusts found underneath the trunk lid rubber seal, and undercarriage.

Has anyone tried Liqui Molly? What are the results? Where to buy it?

Has anyone tried Penetrol (see website below)? What are the results? Where to buy?

You have to cut it out and weld in a new panel, you may be able to buy replacement rust repair panels.

Forget liquid moly, no structrural strength, particularly undercarriage

Penetrol is just a rust converter isnt it? Stops it from spreading, but doesnt fix it.

Gotta cut and put new mate
