I am having massive problems with rust on my '88 SR. After having the arches filled and rust protection applied just 5 months ago, the rust is beginning to come back through! I need advice on getting this major problem sorted! Getting the arches cut out, and new ones welded in seems a bit expensive (?150 per arch!), and tips anyone? Also after taking my bumpers off to get them sprayed I found yet more rust, any advice? I intend on keeping the car for atleast another 3-4yrs so I need long term solutions! Cheers!
