When I lived in Montreal, I Krowned my Elantra for 4 years straight. If you do it every year, they warranty against corrosion for 10 years or something. It was ~80-90 per application, well worth the peace of mind.Not sure if this is in the right section but wanted your opinions on rust proofing and which company from your experience provides the best protection and value.
I know of http://www.krown.com and http://www.rustcheck.com
How often should a vehicle be rust proofed?
Thanks in advance!
