My clear and black samples will be in tomorrow so I will be able to check them out and report on them. They will both handle temps of 700 degrees. The colors however will only handle 250-300 and I was getting temps in the 300 plus range when I tested an engine over the weekend so it looks like the lighter colors will be out but he did say brown, purple and a bronze color will work fine so I am sending in a few more sets to get the purple and see what it looks like and how it holds up to the temps. I was also told that the lighter colors actually darken with the process so he is going to make me up an actual color chart of finished parts so I can see the actual color and texture of the metal when it is done so I can give people better ideas of what they actually look like in finished product form. The thing about the colors is they charge by the lot instead of per piece so the more pieces you do, the cheaper it will be. So I would need at least 10-15 sets to make it even worth doing so there has to be a want for the colors so for now, until I know for sure what people want, I will stick to the clear and black. The black sounds like it will look awesome but you guys will know when I do.
