AFC-50 treatment

[geraldmorrissey]

Well the weather has changed here in the NW so time to spray some primer outside. The only AL items I have to prime are the ailerons and flaps. When I owned an all metal certified airplane, I had it treated with AFC-50 corrosion treatment. Has anyone tried that with fabric covered ailerons and flaps? Deleting primer might save a little counterweight on the ailerons and a ton of work overall. Lots of parts to prime in those assemblies. Not sure what the AFC-50 would do to the fabric.

I would use caution. The fabric gets glued to the structure. I used Stewarts System. Stewarts glue uses a mechanical bond to adhere the fabric to the structure and so it needs to be clean, dry and free of contaminants then scuffed with abrasive. Something like ACF-50 would likely prevent the glue from bonding properly.

I also wonder if ACF50 would soak through the fabric.

My thoughts were to do the fogging after covering. But I'm liking the idea less and less.

Just checked over at Supercub.org. seems like several people use these products successfully on ceconite covered planes with no apparent issues.
