on my legacy the front has a plastic guard that runs all the way around the fender wall. i have always had a problem the the rear fender walls rotting. anyone ever take that plastic guard from the front and trim to fit the rear to keep salt, mud, etc out of there, is it possable.

well then waht keeps the front from rotting?

i've never had a problem with the front rotting. so i was just thinking maybe it has something to do with the guards.

 

i meant get a set from the junk yard for the rear. then i'll have 1 for each wheel well

Fender wells typically rust due to dirt stuck up inside of them which in turns traps moisture. Keeping the inner fender well clear of debris each time you wash your car is something many people overlook. On my vehicles I remove and boots/rings/liners that may trap this dirt each spring and fall and get them good and clean, then give them a shot of rust inhibitor on the inside.
