I'm applying it to my boat now and am really happy with it. Once you start rolling it, it will set up quickly and if it's hot, you should work fast. As soon as it is to the point where you like the way it looks, pull the tape off.
I bought white, but decided it would be to bright so had it tinted at a local paint store to a light tan, came out really nice. Since it isn't their standard base, they won't guarantee it comes out exactly like the sample but it will be really close.
I bought a couple of their rollers, but at $25 they are expensive. Went to Home Depot/Lowes and got orange texture rollers with "loopy-goopy" loops, work just as well at $6. Sometimes the rollers are in the paint section, sometimes in the drywall section.
It is the consistency of mayonase, I scoop globs on an area and spread it with a notched trowel from the home improvement store, something like 3/16 notches, it was the finest I could find there. How thick you spread it contributes to how agressive the tread will be. If it is too agressive just keep rolling it pick up excess and then roll it on the next adjacent area you plan to apply it to. If it isn't as agressive as you like I've put some in a paint tray to get it on the roller and then gone back over an area after it was dry and built it up more.
Keep a bucket of water to put your tools in while you aren't using them, it will set up on them quickly.
