Just bought a new 440i GC and have never rust proofed a car before, since I’ve only owned shitboxes. Got a nice car now and am debating whether or not to get the proofing done. I wash my car pretty much once a week. Ive been told that since i wash the vehicle frequently i should be ok not getting the rust proofing. Is there any truth to that? Should i get the proofing? Any light on this will help, thanks!
