Rust Issue
My car (2004 Honda Accord LX) has some rust on the quarter panel just above the wheels (Please see the attached figure). Some people are telling me that I would need to replace the whole quarter panel for solving this problem, while as per the opinion of others, alternate and cheaper solution apart from changing the quarter panel is also possible. Do I really need to replace the entire quarter panel to remove this rust and make sure that it does not spread any more? FYI, I live in an area which is quite prone to rust problems due to excessive salt use during snowing.
There is another thing I would like to ask. I am not planing to visit a body shop quite soon. Is there any way (like, spraying, etc.) that I can use to temporarily stop or slow down progression of the rust until I will be visiting an auto body shop?
