Corroded aileron brackets

Hello,
My 6 years old RV-8 ( Aluminium Lady) shows some paint strip due to corrosion on steel ailerons bracket, certainly due to proximity of chemical plant acid environnement , and I guess due to lack of durable paint applied in factory
Rudder bracket are also impacted and need to be treated
Do any one of you already find such discrepancy?
( I iiil show pictures as far I find how to...)

After 365 hours, I just replaced the nuts, bolts and washers on my aileron brackets due to corrosion which made them look bad, but probably still safe. My brackets are protected by Imron paint and still look fine.

I powder-coated the brackets on my -6A and no problems after 10 years.
