Covering advice
If you are using Monokote that technique works well. After doing a bit of research I found out that Profilm is actually Oracover, Oracover (Ultracote) shrinks too much at too low a heat setting to make this technique work well. The seams pull apart much more readily then they would with Monokote. Since it is indeed Oracover, it will be easy to put trim over a base color because it's adhesive won't gas and make alot of bubbles like Monokote would.
