Default Pock-marked aluminum


"EASI54" wrote in message
...

Hi Everyone! Thanks for all the responses for my Bondo faring
question.

After sand blasting my aluminum hull, the shallow areas of faring that
remained exposed the bare aluminum of the hull and in some spots there
was this indication of electroloysis or decavitation of the metal that
can be described as "pock marked".

Other than cutting out the damaged area and rewelding, is there any
other approach to repairing the aluminum?

John

John,
Is it a thin hull? That would make a difference between filling or
replacing.
When I worked with sub-launched weapons trainer shapes, we repaired deep
pits (heavy cases on the shapes) with a product 3M made that is an epoxy
with aluminum mixed in. Worked really well and never had any fall out.
This may be the stuff we used but I don't remember the name- been a while.
