Filiform Corrosion?


My trailer has developed a case of filiform corrosion this year (see pic) First year I've seen this.

I've tried the G6, F7, and C Nuvite with the wool bonnet. Also tried the Jestco buffing wheel with gray and red bar.

This white corrosion is pretty persistent.

Anyone have any tricks or suggestions? Sandpaper?

Do a search for posts by "Howard L". This was covered in a series of posts last week regarding treatment, repair, and prevention.

Best of luck.

My comment won't be very helpful I'm afraid, but IMHO, I think what you have is some form of corrosion other than filiform.

I think filiform corrosion - looking like wiggly white worms - is associated with coated aluminum products.

The corrosion develops pathways and inroads under the coating..

Filiform? Most likely not. Corrosion? Definitely! My guess would be that it is from being blasted with sand and salt from winter roads, or the seaside, or the desert (which would have required water afterwards).

Polish it quickly before it eats in too deep. That might not be easy because such white corrosion can be harder than the aluminum.
