Have never heard of them; but in my experience any weathering, whether with powder or paint should be clear coated to help blend it in. You can get small spray bombs of Testors clear coats - just take it out on the deck or just outside and spray it. Krylon also makes different types of clear coat which dries very quickly so you shouldn't have any problems.
