A question has come up about HDO with a customer. He has asked, "Would HDO be appropriate for this application, and last longer than MDO?" I've also gone to my local lumber store to ask about the price of HDO compared to MDO, but unfortunately they don't supply HDO locally. So is there truly an advantage with HDO over MDO and if so, where can I find a supplier?

HDO is High Density Overlay ... it is more like Formica ... MDO is slightly porous overlay.
Originally, it was designed for highway sign because it could take more beating from the weather and weather and things flying off vehicles.
MDO will be good enough for 99% of your needs ... as long as you use the higher grade of MDO, and not the Big Box Store grade ... which is really for making furniture and cabinets.

And just what is wrong with winding up in Canada Si???
It is just fine during the 3 months of summer sometimes.
You know my preference for the other 9 months of the year.

Thanks for the help Si! Much appreciated! I know my way around so it's hard to get lost, but I know lots of people finding themselves crossing over the border on accident!

Brendan, like Si said, HDO was made for applications requiring more outdoor longevity. It is much better quality material, but harder to find.
Additionally, if you use it, take extra time to prep it before painting, or you may have adhesion problems. The surface of HDO is 'slicker than MDO (more like fiberglass resin), and requires a good sanding and cleaning before painting.
