[ARC5] Rebuild or No: A Poll

[Michael Bittner]

It's a tedious job, but it can be done and I've done it, but only when the 
surfaces with the holes are painted.  These surfaces must be cleaned and be 
free of any protrusions that would interfere with a sanding instrument after 
the hole has been filled with a filler compound.  This may mean some major 
disassembly.  Before applying the filler, small holes only need to be 
covered with masking tape on the inside surface, while large holes require 
some backing, such as a piece of scrap aluminum with wax paper on one side 
to prevent the compound from sticking to the backing piece.   Clean the 
holes and their surfaces, apply backing, fill the hole, wait for it to cure, 
sand the filler till it's flush with the outside surface.  Paint the filled 
hole and adjacent surface with matching paint.  If it's wrinkle paint, use 
Dave's trick of using silly putty to match the texture of the newly painted 
area with the existing area.  Finally, remove the backing and you're done.
