Mostly just in the Summer months here Rob would add Propylene Glycol to water and put a thin layer of it in a 30" x 30" plastic tub, and just dunk the veneer a bit before he worked with it. He taught me to buy as pure as possible, food grade. There are a number of offerings at Amazon, and I have found what you get this year, isn't there next year, so I just look them over for the best match, at the lowest price.

Both you guys being a lot hotter down there may need to do that year round, or more dunkings, or a shorter time between dunkings, and application maybe. I would dunk, then used one of those foldable laundry racks to drape it over the rack for about 15 minutes before trying to apply it to my substrate. I almost always used MDF. I'd also lightly paint the MDF with just a bit of the mix because that stuff is like a sponge, and would pull from the veneer.

It would make the veneer softer, so it was much easier to work, and added enough moisture so when dry it didn't curl, crust up, or just misbehave. Sure made working with a piece of thin wood easier to accomplish.
