LOVE this paint!!!
I tried this paint for the very first time this past weekend and OH MY!!
I've used the crackle accents before, and its ok, but this paint ROCKS!! Its soooo cool to watch it crack right before your eyes as it dries!! You can also use your heat gun to speed up the process.
Use a thin coat for a subtle look, paint it on thicker for a more pronounced cracked look. Oh--and the brush is attached to the cap!!
One suggestion, though. If you're using it on a piece that will be handled, I'd suggest protecting it with lamination, diamond glaze, modge podge etc. just so the cracks don't start to flake off.
I'm definitely going to be collecting all the colors they have!!
