Do any of the guys with rust problems have electronic rust proofing or just the painted on stuff????

remove your ceiling light and look for small black gritty bits as this is the panel sealant breaking down the outcome of this is rust where the panel sealant is

Likewise but Ive got a 90 CA lancer with exactly the same problem. Sux because its gotta be the worst place to fix rust. Starting to get sick of all the bloody repairs.
