Hey guys, please don't think I'm trying to rain on your parade, but Scooter Board is basically designed for temporary, short-term use....like a year and a half or less. I would never think of replacing MDO with it. It will break rather easily if you drill near an edge, like where you would put mounting brackets.
Because of its pricing, it is suitable for real estate signs, but will only accept vinyl graphics or some solvent-type screen ink. I haven't found any type of paint that will stick to it, even after sanding. You can't glue two sheets together; I haven't found a glue that will bite and hold it together well. I bought a couple of sheets, and wound up cutting it up and making basically real estate type signs out of it because I determined it wasn't suitable for bigger or better stuff.
I have a technical description sheet that I got from the manufacturer. If you google Scooter Board you may be able to find it, or I'll see if I can come up with it. I talked with the owner of the company about it, and I'm telling you what he told me. Please don't get caught up in the hype of a bunch of salesmen, who are just looking for a commission.
The edges need to be sealed; it appears to be made of pressed sawdust or something; really soaks up moisture.
I haven't been around here much lately, for whatever reason....sorry. But I've been doing this stuff for over 35 years, so I know a little about stuff.
