Going back to the original thread. It's about what you are used to and how you use it. I've got two planes covered in Ultracote and have problems with loosening and lifting regardless of iron temperature setting. In the end you can achieve good results with whatever covering material as long as you take the time to learn how to apply it properly and within its intended temperature range. The inexpensive coverings (Towerkote, Aerokote and others) while saving money in the beginning don't seem to have the same adhesion properties nor do they "work" as easily when being applied to compound curves, etc. Pick something, stick with it and practice.

Here is my last project in Monokote (Steen Skybolt). While it does not have a scale lustre it gives you a good idea of what can be done. I'm working on a 27% scale version and it will be covered in Stitts and dope to match the full scale.
