Rust Proofing Sills and Arches
 

I have a 2004 WRX and live in a small village with muddy lanes. I have realised that despite washing there is mud collecting at the back of the front arches where it joins the side sills.


I want to take the side skirts, inner plastic wheel arches and possible front and rear bumpers off to clean and then spray with rust converter and then dinitrol cavity wax.


I just wondered how far to go with t his. I know the side skirts and inner plastic wheel arches probably aren't too difficult to remove but is it also necessary/worth removing the front and rear bumpers to spray behind at all or is this not necessary?


thanks

Yes do it once , do it properly :)

Thanks, do you know if it is difficult to remove the front and rear bumpers?
