I cn't see it being a bad thing. I remember on another board someone had a little Natty's red and a little blue and melted them together and loved the blended product. you might have a little less solvent afterwords, so it might not cure properly. Let us know what happens when you try it on something.
i was bored and its was little old so it didnt look new lol. im kinda neat freak when it comes to stuff looking good
