It probably works better with the marbilzer paint but I've also experimented with the same method you just did. Looks o.k. I've also tried the same proceedure with aluminum foil. A little harder to do and with a slightly different effect. Looks like yous came out just fine, Chris.:thumbup:
I tried that a couple times and the only problem I came up with was that the top color kinda made the bottom color soft and it pulled the bottom color up as well . Just need to make sure the bottom color is good and dry .
