Proving impossible to track down nice wood like Walnut, etc here in the south of Europe. So have turned my mind in the meantime towards HDU material for making signs, as I hear it cuts really nice, paints well, good longevity and doesn’t like water.
Sorry for the potentially silly question but am I right in thinking a dense Polyurethane is effectively the same material? If so, what type of density am I looking for? If not the same, any suggestions?
Your help is very much appreciated! Thank you.
