Well the above isn't exactly true. The covering material is going to show just about every blemish that is underneath it, so if you have gaps where the materials join it's going to show in the covering. But don't judge it with your eyeballs as looks can be deceiving. Use your hands/fingers as a tool to see if there are imperfections. If you can feel it when you run your hand over it then it's going to show when you put the covering on. It's really that simple. You should strive to have as smooth of a surface that you can get before you put the covering on, otherwise it's going to show through.

Please don't let the above advice about Monokote scare you, many people seem to have the same wrong impressions about it. It's not hard to get wrinkles out of Monokote if you work it correctly. Many give up too quickly on it while they are working the material, and then say that it's no good. I'm not saying there is anything wrong with Ultracote either, I've used both and have good results with both. If asked my preference I prefer to use Monokote because there is a larger selection of colors available, and it's what I have the most experience with.

Obtaining a good job of covering isn't hard, it just takes some time and some practice. Nobody gets a perfect covering job the first time they try. But hang in there and keep working at it and you'll pick it up in no time.

Hope this helps
