Will acetone dissolve it?

Hi there,

There's been lots of talk about putting foam in Ally masts - any ideas
on getting it out - previous owner of boat foamed in wires - PU foam
injected through 1/4" holes at about 6ft intervals. I now want to
replace these, and revert to internal halyards. Mast is 28 ft and only
access is from foot end. I had considered using plastic pipe with the
end cut like a holesaw and twisting, anyone got any other ideas that
won't ruin the anodising?

Thanks in advance,
David. SY Colros.

If the foam is really polyurethane, I don't think acetone or gasoline
will dissolve it rapidly enough. At least I know that polyurethane
coated fabrics used in some dinghies are very resistant to ordinary
chemicals such as acetone and fuels.
