Check with Barnes. I think they have some of the same product lines we have.

Or, you could try Rowe Advanced Materials in S.A. (they are the main distributor of Reynolds/Smooth On's catalogue in Australia). Sorry, Mitch ... Barnes may be well known to most folks down here, but they charge (for a lot of their stuff) almost twice as much as Rowe on some product lines, and - in quite a few situations - you'll ask staff a simple question and get a blank stare in return; your average casual customer knows a lot more than their own staff does. And there were always plenty of places to buy supplies down here, but you had to locate them by yourself, and when you did, you sent as many people to them as possible, just so they could stay in business; those were the places that, after you'd purchased your supplies, whenever you asked an 'interesting' question of them, they'd pop out into the back, grab something similar to what you were asking about ... and ask you to test it for them, and pass on the results to them. That way, they could let other customers know, adding to their own knowledge base.

Thank you!

I have not done any testing with water. That is uncharted territory.

A low density foam like Prop Foam 4 might be a good option. Call us during business hours and we'll see what we can help you with.

It's 15lbs per cubic foot in free rise, but I don't know what that translates to.

I have some arriving this week. I’ll test it and let you know. Four times expansion is my experience with other 15lbs foams.

This doesn't off gas too bad. A well ventilated area is recommended. A respirator is never a bad idea, esp. if you are sensitized to Polyurethanes

Yep. Hard to believe this channel content is older than some of my kids!
