If the rivets are still tight, the procedure would be to clean them of corrosion products manually, then apply brush-on chromate conversion coating, then paint them over. Don’t forget to look at the same places from the inside.
If the rivets have worked themselves loose and are “smoking” (have a smoke-like dark halo around the head), they ought to be replaced.
Txs, found that kind of touch up pen containing Alodine – seems to be a solution for these kind of small areas although maybe not working absolutely accurate but helping to stop corrosion a bit. Quite expensive stuff from a known brand.
@Chris, Alodine (now called Bonderite M-CR) pens work as promised, but are outrageously expensive indeed. A 2-litre kit of two-component brush-on Bonderite M-CR ALCRM 1200BR (formerly Alocrom Brush) in bottles costs less than one pen containing something like 50-75 mL.
@Ultranomad, yes o.k. that sounds to be a good deal but didn´t find a (continental) european shop selling small amounts for a resaonable price though. Still looking around to find a good price to order. Some shops you even have to ask for a quote….strange times right now.
I think those rivets are stainless steel, which is a curious choice on aluminium, no?
I am sure they are original. That is how Socata did it.
I just thought to get to know maybe newer or other measurements to prevent this stuff asap as long the expense is small but looking onto those prices for this kind of patented Alodine containing pen, hm.
